pthread_cleanup_pop(3)					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

SYNOPSIS
       #include <pthread.h>

       int pthread_cleanup_pop(
	       int execute );

LIBRARY
       DECthreads POSIX 1003.1c Library (libpthread.so)

STANDARDS
       Interfaces documented on this reference page conform to industry	 stan‐
       dards 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, cancellation, 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 call‐
       ing 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 corre‐
       sponding right brace (}).

RETURN VALUES
       None
