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.

     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'').
