pthread_setcancelstate - enable or disable cancellation SYNOPSIS
cc -mt [ flag... ] file... -lpthread [ library... ] #include <pthread.h> int pthread_setcancelstate(int state, int *oldstate); DESCRIPTION
The pthread_setcancelstate() function atomically sets the calling thread's cancellation state to the specified state and if oldstate is not NULL, stores the previous cancellation state in oldstate. The state can be either of the following: PTHREAD_CANCEL_ENABLE This is the default. When cancellation is deferred (deferred cancellation is also the default), cancellation occurs when the target thread reaches a cancellation point and a cancel is pending. When cancellation is asynchronous, receipt of a pthread_cancel(3C) call causes immediate cancellation. PTHREAD_CANCEL_DISABLE When cancellation is deferred, all cancellation requests to the target thread are held pending. When cancellation is asynchronous, all cancellation requests to the target thread are held pending; as soon as cancellation is re-enabled, pending cancellations are executed immediately. See cancellation(5) for the definition of a cancellation point and a discussion of cancellation concepts. See pthread_setcanceltype(3C) for explanations of deferred and asynchronous cancellation. RETURN VALUES
Upon successful completion, pthread_setcancelstate(), returns 0. Otherwise, an error number is returned to indicate the error. ERRORS
The pthread_setcancelstate() function will fail if: EINVAL The specified state is not PTHREAD_CANCEL_ENABLE or PTHREAD_CANCEL_DISABLE. ATTRIBUTES
