NAME

       pthread_cancel - cancel execution of a thread

SYNOPSIS

       cc -mt [ flag... ] file... -lpthread [ library... ]
       #include <pthread.h>

       int pthread_cancel(pthread_t target_thread);

       The pthread_cancel() function requests that target_thread be canceled.

       By default, cancellation is deferred until target_thread reaches a cancellation point. See cancellation(5).

       Cancellation  cleanup handlers for target_thread are called when the cancellation is acted on. Upon return of the last cancellation cleanup
       handler, the thread-specific data destructor functions are called for target_thread. target_thread is terminated when the  last	destructor
       function returns.

       The cancellation processing in  target_thread runs asynchronously with respect to the calling thread returning from pthread_cancel().

       If successful, the pthread_cancel() function returns  0. Otherwise, an error number is returned to indicate the error.

       The  pthread_cancel() function may fail if:

       ESRCH	       No thread was found with an ID corresponding to that specified by the given thread ID, target_thread.
