Structs

Name	Description
`_N2`	Content of this structure depends on information which is known and is achievable (e.g. by FTP LIST parsing). Please see the url_easy_setopt(3) man page for callbacks returning this structure -- some fields are mandatory, some others are optional. The FLAG field has special meaning.
`_N28`
`curl_certinfo`	info about the certificate chain, only for OpenSSL builds. Asked for with CURLOPT_CERTINFO / CURLINFO_CERTINFO
`curl_fileinfo`	Content of this structure depends on information which is known and is achievable (e.g. by FTP LIST parsing). Please see the url_easy_setopt(3) man page for callbacks returning this structure -- some fields are mandatory, some others are optional. The FLAG field has special meaning.
`curl_forms`	structure to be used as parameter for CURLFORM_ARRAY
`curl_httppost`
`curl_khkey`
`curl_slist`	linked-list structure for the CURLOPT_QUOTE option (and other)
`curl_sockaddr`	addrlen was a socklen_t type before 7.18.0 but it turned really ugly and painful on the systems that lack this type
`CURLMsg`

Manifest constants

Name	Type	Description
`CURL_ERROR_SIZE`
`CURL_MAX_HTTP_HEADER`		The only reason to have a max limit for this is to avoid the risk of a bad server feeding libcurl with a never-ending header that will cause reallocs infinitely
`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).
`CURL_WRITEFUNC_PAUSE`		This is a magic return code for the write callback that, when returned, will signal libcurl to pause receiving on the current transfer.
`CURLINFO_DOUBLE`
`CURLINFO_HTTP_CODE`		CURLINFO_RESPONSE_CODE is the new name for the option previously known as CURLINFO_HTTP_CODE
`CURLINFO_LONG`
`CURLINFO_MASK`
`CURLINFO_SLIST`
`CURLINFO_STRING`
`CURLINFO_TYPEMASK`
`CURLM_CALL_MULTI_SOCKET`		just to make code nicer when using curl_multi_socket() you can now check for CURLM_CALL_MULTI_SOCKET too in the same style it works for curl_multi_perform() and CURLM_CALL_MULTI_PERFORM
`CURLOPT_HEADERDATA`		three convenient "aliases" that follow the name scheme better
`CURLOPT_READDATA`		three convenient "aliases" that follow the name scheme better
`CURLOPT_RTSPHEADER`		three convenient "aliases" that follow the name scheme better
`CURLOPT_SERVER_RESPONSE_TIMEOUT`
`CURLOPT_WRITEDATA`		three convenient "aliases" that follow the name scheme better
`CURLOPTTYPE_FUNCTIONPOINT`		long may be 32 or 64 bits, but we should never depend on anything else but 32
`CURLOPTTYPE_LONG`		long may be 32 or 64 bits, but we should never depend on anything else but 32
`CURLOPTTYPE_OBJECTPOINT`		long may be 32 or 64 bits, but we should never depend on anything else but 32
`CURLOPTTYPE_OFF_T`		long may be 32 or 64 bits, but we should never depend on anything else but 32
`CURLVERSION_NOW`		The 'CURLVERSION_NOW' is the symbolic name meant to be used by basically all programs ever that want to get version information. It is meant to be a built-in version number for what kind of struct the caller expects. If the struct ever changes, we redefine the NOW to another enum from above.
`HTTPPOST_BUFFER`		upload file from buffer
`HTTPPOST_CALLBACK`		upload file contents by using the regular read callback to get the data and pass the given pointer as custom pointer
`HTTPPOST_FILENAME`		specified content is a file name
`HTTPPOST_PTRBUFFER`		upload file from pointer contents
`HTTPPOST_PTRCONTENTS`		contents is only stored pointer do not free in formfree
`HTTPPOST_PTRNAME`		name is only stored pointer do not free in formfree
`HTTPPOST_READFILE`		specified content is a file name
`LIBCURL_COPYRIGHT`		This is the global package copyright
`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.
`LIBCURL_VERSION`		This is the version number of the libcurl package from which this header file origins:
`LIBCURL_VERSION_MAJOR`		The numeric version number is also available "in parts" by using these constants
`LIBCURL_VERSION_MINOR`		The numeric version number is also available "in parts" by using these constants
`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:
`LIBCURL_VERSION_PATCH`		The numeric version number is also available "in parts" by using these constants

Name	Type	Description
`CURL`	`void`
`curl_calloc_callback`	`void* function(ulong, ulong)`	The following typedef's are signatures of malloc, free, realloc, strdup and calloc respectively. Function pointers of these types can be passed to the curl_global_init_mem() function to set user defined memory management callback routines.
`curl_chunk_bgn_callback`	`long function(const(void), void, int)`	if splitting of data transfer is enabled, this callback is called before download of an individual chunk started. Note that parameter "remains" works only for FTP wildcard downloading (for now), otherwise is not used
`curl_chunk_end_callback`	`long function(void*)`	If splitting of data transfer is enabled this callback is called after download of an individual chunk finished. Note! After this callback was set then it have to be called FOR ALL chunks. Even if downloading of this chunk was skipped in CHUNK_BGN_FUNC. This is the reason why we don't need "transfer_info" parameter in this callback and we are not interested in "remains" parameter too.
