Module `core.thread.threadbase`

The threadbase module provides OS-independent code for thread storage and management.

Functions

Name	Description
`findLowLevelThread(tid)`	Check whether a thread was created by `createLowLevelThread`.
`thread_detachByAddr(addr)`	Deregisters the given thread from use with the runtime. If this routine is called for a thread which is not registered, the result is undefined.
`thread_detachInstance(t)`	Deregisters the given thread from use with the runtime. If this routine is called for a thread which is not registered, the result is undefined.
`thread_detachThis()`	Deregisters the calling thread from use with the runtime. If this routine is called for a thread which is not registered, the result is undefined.
`thread_enterCriticalRegion()`	Signals that the code following this call is a critical region. Any code in this region must finish running before the calling thread can be suspended by a call to thread_suspendAll.
`thread_exitCriticalRegion()`	Signals that the calling thread is no longer in a critical region. Following a call to this function, the thread can once again be suspended.
`thread_findByAddr(addr)`	Search the list of all threads for a thread with the given thread identifier.
`thread_inCriticalRegion()`	Returns true if the current thread is in a critical region; otherwise, false.
`thread_isMainThread()`
`thread_joinAll()`	Joins all non-daemon threads that are currently running. This is done by performing successive scans through the thread list until a scan consists of only daemon threads.
`thread_processGCMarks(isMarked)`	This routine allows the runtime to process any special per-thread handling for the GC. This is needed for taking into account any memory that is referenced by non-scanned pointers but is about to be freed. That currently means the array append cache.
`thread_resumeAll()`	Resume all threads but the calling thread for "stop the world" garbage collection runs. This function must be called once for each preceding call to thread_suspendAll before the threads are actually resumed.
`thread_scanAll(scan)`	The main entry point for garbage collection. The supplied delegate will be passed ranges representing both stack and register values.
`thread_scanAllType(scan)`	The main entry point for garbage collection. The supplied delegate will be passed ranges representing both stack and register values.
`thread_setThis(t)`	Sets the current thread to a specific reference. Only to be used when dealing with externally-created threads (in e.g. C code). The primary use of this function is when ThreadBase.getThis() must return a sensible value in, for example, TLS destructors. In other words, don't touch this unless you know what you're doing.
`thread_stackBottom()`	Returns the stack bottom of the currently active stack within the calling thread.
`thread_stackTop()`	Returns the stack top of the currently active stack within the calling thread.

Classes

Name	Description
`ThreadBase`
`ThreadError`	Base class for thread errors to be used for function inside GC when allocations are unavailable.
`ThreadException`	Base class for thread exceptions.

Enums

Name	Description
`IsMarked`	Indicates whether an address has been marked by the GC.
`ScanType`	Indicates the kind of scan being performed by `thread_scanAllType`.

Aliases

Name	Type	Description
`IsMarkedDg`	`int delegate(void*)`	The isMarked callback function.
`ScanAllThreadsFn`	`void delegate(void, void)`	The scanning function.
`ScanAllThreadsTypeFn`	`void delegate(ScanType, void, void)`	The scanning function.
