Standard C Library Functions pthread_cancel(3C)
NAME
pthread_cancel - cancel execution of a thread
SYNOPSIS
cc -mt [ flag... ] file... -lpthread [ library... ]
#include
int pthread_cancel(pthread_t target_thread);
DESCRIPTION
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 lastcancellation cleanup handler, the thread-specific data des-
tructor functions are called for target_thread.
target_thread is terminated when the last destructor func-
tion returns.A thread acting on a cancellation request runs with all sig-
nals blocked. All thread termination functions, includingcancellation cleanup handlers and thread-specific data des-
tructor functions, are called with all signals blocked.The cancellation processing in target_thread runs asynchro-
nously with respect to the calling thread returning frompthread_cancel().
RETURN VALUES
If successful, the pthread_cancel() function returns 0.
Otherwise, an error number is returned to indicate the error.ERRORS
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.
