PTHREAD_CLEANUP_PUSH(3) BSD Library Functions Manual PTHREAD_CLEANUP_PUSH(3) NAME
pthread_cleanup_push -- add a cleanup function for thread exit SYNOPSIS
#include <pthread.h> void pthread_cleanup_push(void (*routine)(void *), void *arg); DESCRIPTION
The pthread_cleanup_push() function adds routine to the top of the stack of cleanup handlers that get called when the current thread exits. When routine is called, it is passed arg as its only argument. pthread_cleanup_push() must be paired with a corresponding pthread_cleanup_pop(3) in the same lexical scope. RETURN VALUES
pthread_cleanup_push() does not return any value. ERRORS
None SEE ALSO
pthread_cleanup_pop(3), pthread_exit(3) STANDARDS
pthread_cleanup_push() conforms to ISO/IEC 9945-1:1996 (``POSIX.1''). BSD

pthread_cleanup_push(3) Library Functions Manual pthread_cleanup_push(3) NAME
pthread_cleanup_push - (Macro) Establishes a cleanup handler routine to be executed when the thread exits or is canceled. LIBRARY
DECthreads POSIX 1003.1c Library (libpthread.so) SYNOPSIS
#include <pthread.h> int pthread_cleanup_push( void (*routine)(void *), void *arg); STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: IEEE Std 1003.1c-1995, POSIX System Application Program Interface PARAMETERS
Routine executed as the cleanup handler. Argument passed to the cleanup routine. DESCRIPTION
This routine pushes the specified routine onto the calling thread's cleanup handler stack. The cleanup handler routine is popped from the stack and 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_pop(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 (}).
