Use the -l c option to qcc to link against this library. This library is usually included automatically.
Description:
The pthread_cleanup_pop() macro pops the top cancellation-cleanup handler from the calling thread's cancellation-cleanup stack and invokes the handler if execute is nonzero.
Note:
The pthread_cleanup_pop() macro expands to a few lines of code
that end with a closing brace (
}), but don't have a matching
opening brace ({).
You must pair pthread_cleanup_pop() with
pthread_cleanup_push()
within the same lexical scope.
