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 (*cleanup_routine)(void *), void *arg);


DESCRIPTION

     The pthread_cleanup_push() function adds cleanup_routine to the top of
     the stack of cleanup handlers that get called when the current thread
     exits.

     When cleanup_routine is called, it is passed arg as its only argument.

     The pthread_cleanup_push() function is implemented as a macro that opens
     a new block.  Invocations of this function must appear as standalone
     statements that are paired with a later call of pthread_cleanup_pop(3) in
     the same lexical scope.


RETURN VALUES

     The pthread_cleanup_push() function does not return any value.


ERRORS

     None


SEE ALSO

     pthread_cleanup_pop(3), pthread_exit(3)


STANDARDS

     The pthread_cleanup_push() function conforms to ISO/IEC 9945-1:1996
     (``POSIX.1'').
