NAME

6       pthread_testcancel  -  request  delivery  of  any  pending cancellation
7       request
8

SYNOPSIS

12       void pthread_testcancel(void);
13
14       Compile and link with -pthread.

DESCRIPTION

17       Calling pthread_testcancel() creates a cancellation  point  within  the
18       calling  thread, so that a thread that is otherwise executing code that
19       contains no cancellation points will respond to a cancellation request.
20
21       If cancelability is disabled (using pthread_setcancelstate(3)),  or  no
22       cancellation request is pending, then a call to pthread_cancel() has no
23       effect.
24

27       celed  as  a  consequence of a call to this function, then the function
28       does not return.
