NAME

       pthread_cancel - cancel execution of a thread

SYNOPSIS

       cc -mt [ flag... ] file... -lpthread [ library... ]
       #include <pthread.h>

       int pthread_cancel(pthread_t target_thread);

       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 last cancellation cleanup
       handler, the thread-specific data destructor functions are called for target_thread. target_thread is terminated when the  last	destructor
       function returns.

       The cancellation processing in  target_thread runs asynchronously with respect to the calling thread returning from pthread_cancel().

       If successful, the pthread_cancel() function returns  0. Otherwise, an error number is returned to indicate the error.

       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.

NAME

       pthread_cleanup_push - push a thread cancellation cleanup handler

SYNOPSIS

       cc -mt [ flag... ] file... -lpthread [ library... ]
       #include <pthread.h>

       void pthread_cleanup_push(void (*handler, void *),void *arg);

       The pthread_cleanup_push() function pushes the specified cancellation cleanup handler routine, handler, onto the cancellation cleanup stack
       of the calling thread.

       When a thread exits or is canceled and its cancellation cleanup	stack is not empty, the cleanup handlers are  invoked  with  the  argument
       arg in  last in, first out (LIFO) order from the cancellation cleanup stack.

       The pthread_cleanup_push() and pthread_cleanup_pop(3C) functions can be implemented as macros. The application must ensure that they appear
       as statements, and in pairs within the same lexical scope (that is, the pthread_cleanup_push() macro can be thought to expand  to  a  token
       list whose first token is '{' with pthread_cleanup_pop() expanding to a token list whose last token is the corresponding '}').

       The  effect of the use of return, break, continue, and goto to prematurely leave a code block described by a pair of pthread_cleanup_push()
       and pthread_cleanup_pop() function calls is undefined.

       Using longjmp() or siglongjmp() to jump into or out of a push/pop pair can cause either the matching push or the matching pop statement not
       getting executed.

       The pthread_cleanup_push() function returns no value.

       No errors are defined.

       The  pthread_cleanup_push() function will not return an error code of EINTR.
