/* DESCRIPTION */
|
|
/* */
|
|
/* The pthread_testcancel function shall request that thread be */
|
|
/* canceled if the cancel state is enabled and cancel type is */
|
|
/* deferred, and a cancellation request has happened in the past. */
|
|
/* The target thread's cancelability state and type determines when */
|
|
/* the cancellation takes effect. When the cancellation is acted on, */
|
|
/* the cancelation cleanup handlers for thread shall be called. When */
|
|
/* the last cancelation cleanup handler returns, the thread-specific */
|
|
/* data destructor functions shall be called for thread. When the last */
|
|
/* destructor function returns, thread shall be terminated. */
|
|
/* */

/* thread pthread handle to thread to be canceled */
