Requests the cancellation of a thread.
Threads Library (libpthreads.a)
int pthread_cancel (pthread_t thread);
The pthread_cancel subroutine requests the cancellation of the thread thread. The action depends on the cancelability of the target thread:
The cancellation of a thread terminates it safely, using the same termination procedure as the pthread_exit subroutine.
Note: The pthread.h header file must be the first included file of each source file using the threads library. Otherwise, the -D_THREAD_SAFE compilation flag should be used, or the cc_r compiler used. In this case, the flag is automatically set.
|thread||Specifies the thread to be canceled.|
If successful, the pthread_cancel function returns zero. Otherwise, an error number is returned to indicate the error.
The ptread_cancel function may fail if:
|ESRCH||No thread could be found corresponding to that specified by the given thread ID.|
The pthread_cancel function will not return an error code of EINTR.
This subroutine is part of the Base Operating System (BOS) Runtime.
