pthread_cleanup_pop(3)					     Library Functions Manual					    pthread_cleanup_pop(3)

NAME
       pthread_cleanup_pop  -  (Macro) Removes the cleanup handler routine from the calling thread's cleanup handler stack and optionally executes
       it.

LIBRARY
       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS
       #include <pthread.h>

       int pthread_cleanup_pop(
			 int	execute);

STANDARDS
       Interfaces documented on this reference page conform to industry standards as follows:

       IEEE Std 1003.1c-1995, POSIX System Application Program Interface

PARAMETERS
       Integer that specifies whether the cleanup handler routine specified in the  matching  call  to	pthread_cleanup_push(3)  is  executed.	 A
       nonzero value causes the cleanup handler routine to be executed.

DESCRIPTION
       This  routine  removes  the  cleanup  handler routine established by the matching call to pthread_cleanup_push(3) from the calling thread's
       cleanup handler stack, then executes it if the value specified in this routine's execute argument is nonzero.

       A cleanup handler routine can be used to clean up from a block of code whether exited by normal completion, cancelation, or the raising (or
       reraising)  of  an  exception.  The routine is popped from the calling thread's cleanup handler stack and is executed with the arg argument
       when any of the following actions occur: The thread calls pthread_cleanup_pop(3) and specifies a nonzero value for  the	execute  argument.
       The  thread  calls  pthread_exit(3).   The  thread  is  canceled.  An exception is raised and is caught when DECthreads unwinds the calling
       thread's  stack	to  the  lexical  scope  of   the   pthread_cleanup_push(3)   and   pthread_cleanup_pop(3)   pair.    This   routine   and
       pthread_cleanup_push(3)	are implemented as macros and must appear as statements and in pairs within the same lexical scope.  You can think
       of the pthread_cleanup_push(3) macro as expanding to a string whose first character is a  left  brace  ({)  and	pthread_cleanup_pop(3)	as
       expanding to a string containing the corresponding right brace (}).

RETURN VALUES
       None
