pthread_cancel(3P)

NAME
     pthread_cancel - request cancellation of a thread

C SYNOPSIS
     #include <pthread.h>

     int pthread_cancel(pthread_t thread);

DESCRIPTION
     The pthread_cancel() function requests that the thread identified by
     thread be cancelled.  Cancellation state [see pthread_setcancelstate()]
     and type [see pthread_setcanceltype()] determine whether the request is
     acted upon immediately or at some time in the future; pthread_cancel()
     does not wait, it merely issues the request.  When thread does act on the
     request, it will terminate as if it had called pthread_exit() with a
     return status of PTHREAD_CANCELED.

DIAGNOSTICS
     On success pthread_cancel() returns zero; otherwise an error number is
     returned:

     [ESRCH]        The thread parameter does not identify a thread.
