; - This is the version number of the libcurl package from which this header file origins:
- enum int
LIBCURL_VERSION_MAJOR
;
enum intLIBCURL_VERSION_MINOR
;
enum intLIBCURL_VERSION_PATCH
; - The numeric version number is also available "in parts" by using these constants
- enum int
LIBCURL_VERSION_NUM
; - This is the numeric version of the libcurl version number, meant for easier parsing and comparions by programs. The LIBCURL_VERSION_NUM define will always follow this syntax:0xXXYYZZ Where XX, YY and ZZ are the main version, release and patch numbers in hexadecimal (using 8 bits each). All three numbers are always represented using two digits. 1.2 would appear as "0x010200" while version 9.11.7 appears as "0x090b07". This 6-digit (24 bits) hexadecimal number does not show pre-release number, and it is always a greater number in a more recent release. It makes comparisons with greater than and less than work.
- enum string
LIBCURL_TIMESTAMP
; - This is the date and time when the full source package was created. The timestamp is not stored in git, as the timestamp is properly set in the tarballs by the maketgz script.The format of the date should follow this template: "Mon Feb 12 11:35:33 UTC 2007"

curl_off_t
= long; - Data type definition of curl_off_t.jdrewsen - Always 64bit signed and that is what long is in D. Comment below is from curlbuild.h: NOTE 2: For any given platform/compiler curl_off_t must be typedef'ed to a 64-bit wide signed integral data type. The width of this data type must remain constant and independent of any possible large file support settings. As an exception to the above, curl_off_t shall be typedef'ed to a 32-bit wide signed integral data type if there is no 64-bit type.

CURL_MAX_WRITE_SIZE
; - Tests have proven that 20K is a very bad buffer size for uploads on Windows, while 16K for some odd reason performed a lot better. We do the ifndef check to allow this value to easier be changed at build time for those who feel adventurous. The practical minimum is about 400 bytes since libcurl uses a buffer of this size as a scratch area (unrelated to network send operations).

- The full URL to get/put
port
- Port number to connect to, if other than default.
proxy
- Name of proxy to use.
userpwd
- "name:password" to use when fetching.
proxyuserpwd
- "name:password" to use with proxy.
range
- Range to get, specified as an ASCII string.
infile
- not usedSpecified file stream to upload from (use as input):
errorbuffer
- Buffer to receive error messages in, must be at least CURL_ERROR_SIZE bytes big. If this is not used, error messages go to stderr instead:
writefunction
- Function that will be called to store the output (instead of fwrite). The parameters will use fwrite() syntax, make sure to follow them.
readfunction
- Function that will be called to read the input (instead of fread). The parameters will use fread() syntax, make sure to follow them.
timeout
- Time-out the read operation after this amount of seconds
infilesize
- If the CURLOPT_INFILE is used, this can be used to inform libcurl about how large the file being sent really is. That allows better error checking and better verifies that the upload was successful. -1 means unknown size.For large file support, there is also a LARGE version of the key which takes an off_t type, allowing platforms with larger off_t sizes to handle larger files. See below for INFILESIZE_LARGE.
postfields
- POST static input fields.
referer
- Set the referrer page (needed by some CGIs)
ftpport
- Set the FTP PORT string (interface name, named or numerical IP address) Use i.e '-' to use default address.
useragent
- Set the User-Agent string (examined by some CGIs)
low_speed_limit
- If the download receives less than "low speed limit" bytes/second during "low speed time" seconds, the operations is aborted. You could i.e if you have a pretty high speed connection, abort if it is less than 2000 bytes/sec during 20 seconds.Set the "low speed limit"
low_speed_time
- Set the "low speed time"
resume_from
- Set the continuation offset.Note there is also a LARGE version of this key which uses off_t types, allowing for large file offsets on platforms which use larger-than-32-bit off_t's. Look below for RESUME_FROM_LARGE.
cookie
- Set cookie in request:
httpheader
- This points to a linked list of headers, struct curl_slist kind
httppost
- This points to a linked list of post entries, struct curl_httppost
sslcert
- name of the file keeping your private SSL-certificate
keypasswd
- password for the SSL or SSH private key
crlf
- send TYPE parameter?
quote
- send linked-list of QUOTE commands
writeheader
- send FILE * or void * to store headers to, if you use a callback it is simply passed to the callback unmodified
cookiefile
- point to a file to read the initial cookies from, also enables "cookie awareness"
sslversion
- What version to specifically try to use. See CURL_SSLVERSION defines below.
timecondition
- What kind of HTTP time condition to use, see defines
timevalue
- Time to use with the above condition. Specified in number of seconds since 1 Jan 1970
customrequest
- Custom request, for customizing the get command like
HTTP DELETE, TRACE and others
FTP to use a different list command
stderr
- HTTP request, for odd commands like DELETE, TRACE and others
postquote
- send linked-list of post-transfer QUOTE commands
writeinfo
- Pass a pointer to string of the output using full variable-replacement as described elsewhere.
verbose
- talk a lot
header
- throw the header out too
noprogress
- shut off the progress meter
nobody
- use HEAD to get http document
failonerror
- no output on http error codes >= 300
upload
- this is an upload
post
- HTTP POST method
dirlistonly
- return bare names when listing directories
append
- Append instead of overwrite on upload!
netrc
- Specify whether to read the user+password from the .netrc or the URL. This must be one of the CURL_NETRC_* enums below.
followlocation
- use Location: Luke!
transfertext
- transfer data in text/ASCII format
put
- HTTP PUT
progressfunction
- Function that will be called instead of the internal progress display function. This function should be defined as the curl_progress_callback prototype defines.
progressdata
- Data passed to the progress callback
autoreferer
- We want the referrer field set automatically when following locations
proxyport
- Port of the proxy, can be set in the proxy string as well with: [host]:[port]
postfieldsize
- size of the POST input data, if strlen() is not good to use
httpproxytunnel
- tunnel non-http operations through a HTTP proxy
intrface
- Set the interface string to use as outgoing network interface
krblevel
- Set the krb4/5 security level, this also enables krb4/5 awareness. This is a string, 'clear', 'safe', 'confidential' or 'private'. If the string is set but doesn't match one of these, 'private' will be used.
ssl_verifypeer
- Set if we should verify the peer in ssl handshake, set 1 to verify.
cainfo
- The CApath or CAfile used to validate the peer certificate this option is used only if SSL_VERIFYPEER is true
maxredirs
- Maximum number of http redirects to follow
filetime
- Pass a long set to 1 to get the date of the requested document (if possible)! Pass a zero to shut it off.
telnetoptions
- This points to a linked list of telnet options
maxconnects
- Max amount of cached alive connections
closepolicy
- What policy to use when closing connections when the cache is filled up
fresh_connect
- Set to explicitly use a new connection for the upcoming transfer. Do not use this unless you're absolutely sure of this, as it makes the operation slower and is less friendly for the network.
forbid_reuse
- Set to explicitly forbid the upcoming transfer's connection to be re-used when done. Do not use this unless you're absolutely sure of this, as it makes the operation slower and is less friendly for the network.
random_file
- Set to a file name that contains random data for libcurl to use to seed the random engine when doing SSL connects.
egdsocket
- Set to the Entropy Gathering Daemon socket pathname
connecttimeout
- Time-out connect operations after this amount of seconds, if connects are OK within this time, then fine... This only aborts the connect phase. [Only works on unix-style/SIGALRM operating systems]
headerfunction
- Function that will be called to store headers (instead of fwrite). The parameters will use fwrite() syntax, make sure to follow them.
httpget
- Set this to force the HTTP request to get back to GET. Only really usable if POST, PUT or a custom request have been used first.
ssl_verifyhost
- Set if we should verify the Common name from the peer certificate in ssl handshake, set 1 to check existence, 2 to ensure that it matches the provided hostname.

share
- Provide a CURLShare for mutexing non-ts data
proxytype
- indicates type of proxy. accepted values are CURLPROXY_HTTP (default), CURLPROXY_SOCKS4, CURLPROXY_SOCKS4A and CURLPROXY_SOCKS5.

- Set this option to one of the CURL_IPRESOLVE_* defines (see below) to tell libcurl to resolve names to those IP versions only. This only has affect on systems with support for more than one, i.e IPv4 and_ IPv6.
maxfilesize
- Set this option to limit the size of a file that will be downloaded from an HTTP or FTP server.Note there is also LARGE version which adds large file support for platforms which have larger off_t sizes. See MAXFILESIZE_LARGE below.
infilesize_large
- See the comment for INFILESIZE above, but in short, specifies the size of the file being uploaded. -1 means unknown.
resume_from_large
- Sets the continuation offset. There is also a LONG version of this; look above for RESUME_FROM.
maxfilesize_large
- Sets the maximum size of data that will be downloaded from an HTTP or FTP server. See MAXFILESIZE above for the LONG version.
netrc_file
- Set this option to the file name of your .netrc file you want libcurl to parse (using the CURLOPT_NETRC option). If not set, libcurl will do a poor attempt to find the user's home directory and check for a .netrc file in there.
use_ssl

tcp_nodelay
- Enable/disable the TCP Nagle algorithm
ftpsslauth
- When FTP over SSL/TLS is selected (with CURLOPT_USE_SSL), this option can be used to change libcurl's default action which is to first try "AUTH SSL" and then "AUTH TLS" in this order, and proceed when a OK response has been received.Available parameters are: CURLFTPAUTH_DEFAULT - let libcurl decide CURLFTPAUTH_SSL - try "AUTH SSL" first, then TLS CURLFTPAUTH_TLS - try "AUTH TLS" first, then SSL

ftp_filemethod
- Select "file method" to use when doing FTP, see the curl_ftpmethod above.
localport
- Local port number to bind the socket to
localportrange
- Number of ports to try, including the first one set with LOCALPORT. Thus, setting it to 1 will make no additional attempts but the first.

new_file_perms
new_directory_perms
- Permission used when creating new files and directories on the remote server for protocols that support it, SFTP/SCP/FILE
postredir
- Set the behaviour of POST when redirecting. Values must be set to one of CURL_REDIR* defines below. This used to be called CURLOPT_POST301
ssh_host_public_key_md5
- used by scp/sftp to verify the host's public key

- "name" and "pwd" to use with Proxy when fetching.
noproxy
- Comma separated list of hostnames defining no-proxy zones. These should match both hostnames directly, and hostnames within a domain. For example, local.com will match local.com and www.local.com, but NOT notlocal.com or www.notlocal.com. For compatibility with other implementations of this, .local.com will be considered to be the same as local.com. A single * is the only valid wildcard, and effectively disables the use of proxy.

- block size for TFTP transfers
socks5_gssapi_service
- Socks Service
socks5_gssapi_nec

protocols
- set the bitmask for the protocols that are allowed to be used for the transfer, which thus helps the app which takes URLs from users or other external inputs and want to restrict what protocol(s) to deal with. Defaults to CURLPROTO_ALL.
redir_protocols
- set the bitmask for the protocols that libcurl is allowed to follow to, as a subset of the CURLOPT_PROTOCOLS ones. That means the protocol needs to be set in both bitmasks to be allowed to get redirected to. Defaults to all protocols except FILE and SCP.

curl_multi_init
(); Name curl_multi_init()
Desc inititalize multi-style curl usage
Returns:a new CURLM handle to use in all 'curl_multi' functions.- CURLMcode
curl_multi_add_handle
(CURLM*multi_handle
, CURL*curl_handle
); Name curl_multi_add_handle()
Desc add a standard curl handle to the multi stack
Returns:CURLMcode type, general multi error code.- CURLMcode
curl_multi_remove_handle
(CURLM*multi_handle
, CURL*curl_handle
); Name curl_multi_remove_handle()
Desc removes a curl handle from the multi stack again
Returns:CURLMcode type, general multi error code.- alias
fd_set
= int; Name curl_multi_fdset()
Desc Ask curl for its fd_set sets. The app can use these to select() or poll() on. We want curl_multi_perform() called as soon as one of them are ready.
Returns:CURLMcode type, general multi error code. tmp decl- CURLMcode
curl_multi_fdset

, fd_set*exc_fd_set
, int*max_fd
); - CURLMcode
curl_multi_perform
(CURLM*multi_handle
, int*running_handles
); Name curl_multi_perform()
Desc When the app thinks there's data available for curl it calls this function to read/write whatever there is right now. This returns as soon as the reads and writes are done. This function does not require that there actually is data available for reading or that data can be written, it can be called just in case. It returns the number of handles that still transfer data in the second argument's integer-pointer.
Returns:CURLMcode type, general multi error code. NOTE that this only returns errors etc regarding the whole multi stack. There might still have occurred problems on invidual transfers even when this returns OK.- CURLMcode
curl_multi_cleanup
(CURLM*multi_handle
); Name curl_multi_cleanup()
Desc Cleans up and removes a whole multi stack. It does not free or touch any individual easy handles in any way. We need to define in what state those handles will be if this function is called in the middle of a transfer.
Returns:CURLMcode type, general multi error code.- CURLMsg*
curl_multi_info_read
(CURLM*multi_handle
, int*msgs_in_queue
); Name curl_multi_info_read()
Desc Ask the multi handle if there's any messages/informationals from the individual transfers. Messages include informationals such as error code from the transfer or just the fact that a transfer is completed. More details on these should be written down as well.
Repeated calls to this function will return a new struct each time, until a special "end of msgs" struct is returned as a signal that there is no more to get at this point. The data the returned pointer points to will not survive calling curl_multi_cleanup(). The 'CURLMsg' struct is meant to be very simple and only contain very basic informations. If more involved information is wanted, we will provide the particular "transfer handle" in that struct and that should/could/would be used in subsequent curl_easy_getinfo() calls (or similar). The point being that we must never expose complex structs to applications, as then we'll undoubtably get backwards compatibility problems in the future.Returns:A pointer to a filled-in struct, or NULL if it failed or ran out of structs. It also writes the number of messages left in the queue (after this read) in the integer the second argument points to.- const(char)*
curl_multi_strerror
(CURLMcode); Name curl_multi_strerror()
Desc The curl_multi_strerror function may be used to turn a CURLMcode value into the equivalent human readable error string. This is useful for printing meaningful error messages.
Returns:A pointer to a zero-terminated error message.- enum
CurlPoll
: int; Name curl_multi_socket() and curl_multi_socket_all()
Desc An alternative version of curl_multi_perform() that allows the application to pass in one of the file descriptors that have been detected to have "action" on them and let libcurl perform. See man page for details.
