NAME

pthread_testcancel − request delivery of any pending cancelation request

LIBRARY

POSIX threads library (libpthread, −lpthread)

SYNOPSIS

#include <pthread.h>

void pthread_testcancel(void);

DESCRIPTION

Calling pthread_testcancel() creates a cancelation point within the calling thread, so that a thread that is otherwise executing code that contains no cancelation points will respond to a cancelation request.

If cancelability is disabled (using pthread_setcancelstate(3)), or no cancelation request is pending, then a call to pthread_testcancel() has no effect.

RETURN VALUE

This function does not return a value. If the calling thread is canceled as a consequence of a call to this function, then the function does not return.

ERRORS

This function always succeeds.

ATTRIBUTES

For an explanation of the terms used in this section, see attributes(7).

HISTORY

glibc 2.0. POSIX.1-2001.

EXAMPLES
