Overview
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.
