Module `core.thread.osthread`

The osthread module provides low-level, OS-dependent code for thread creation and management.

Functions

Name	Description
`createLowLevelThread(dg, stacksize, cbDllUnload)`	Create a thread not under control of the runtime, i.e. TLS module constructors are not run and the GC does not suspend it during a collection.
`joinLowLevelThread(tid)`	Wait for a thread created with `createLowLevelThread` to terminate.
`thread_attachThis()`	Registers the calling thread for use with the D Runtime. If this routine is called for a thread which is already registered, no action is performed.
`thread_init()`	Initializes the thread module. This function must be called by the garbage collector on startup and before any other thread routines are called.
`thread_setGCSignals(suspendSignalNo, resumeSignalNo)`	Instruct the thread module, when initialized, to use a different set of signals besides SIGUSR1 and SIGUSR2 for suspension and resumption of threads. This function should be called at most once, prior to thread_init(). This function is Posix-only.
`thread_suspendAll()`	Suspend all threads but the calling thread for "stop the world" garbage collection runs. This function may be called multiple times, and must be followed by a matching number of calls to thread_resumeAll before processing is resumed.
`thread_term()`	Terminates the thread module. No other thread routine may be called afterwards.

Classes

Name	Description
`Thread`	This class encapsulates all threading functionality for the D programming language. As thread manipulation is a required facility for garbage collection, all user threads should derive from this class, and instances of this class should never be explicitly deleted. A new thread may be created using either derivation or composition, as in the following example.

Aliases

Name	Type	Description
`getpid`	`core.sys.posix.unistd.getpid`	Returns the process ID of the calling process, which is guaranteed to be unique on the system. This call is always successful.
