STK thread class.
This class provides a uniform interface for cross-platform threads. On unix systems, the pthread library is used. Under Windows, the C runtime threadex functions are used.
Each instance of the Thread class can be used to control a single thread process. Routines are provided to signal cancelation and/or joining with a thread, though it is not possible for this class to know the running status of a thread once it is started.
For cross-platform compatability, thread functions should be declared as follows:
THREAD_RETURN THREAD_TYPE thread_function(void *ptr)
by Perry R. Cook and Gary P. Scavone, 1995–2021.
|void *||ptr =
Begin execution of the thread routine. Upon success, true is returned.
A data pointer can be supplied to the thread routine via the optional ptr argument. If the thread cannot be created, the return value is false.
Signal cancellation of a thread routine, returning true on success.
This function only signals thread cancellation. It does not wait to verify actual routine termination. A true return value only signifies that the cancellation signal was properly executed, not thread cancellation. A thread routine may need to make use of the testCancel() function to specify a cancellation point.
Block the calling routine indefinitely until the thread terminates.
This function suspends execution of the calling routine until the thread has terminated. It will return immediately if the thread was already terminated. A true return value signifies successful termination. A false return value indicates a problem with the wait call.
Create a cancellation point within a thread routine.
This function call checks for thread cancellation, allowing the thread to be terminated if a cancellation request was previously signaled.
