pthread_cleanup_pop -- call the first cleanup routine
#include <pthread.h> void pthread_cleanup_pop(int execute);
The pthread_cleanup_pop() function pops the top cleanup routine off of the current threads cleanup routine stack, and, if execute is non-zero, it will execute the function. If there is no cleanup routine then pthread_cleanup_pop() does nothing. The pthread_cleanup_pop() function is implemented as a macro that closes a block. Invocations of this function must appear as standalone state- ments that are paired with an earlier call of pthread_cleanup_push(3) in the same lexical scope.
The pthread_cleanup_pop() function does not return any value.
The pthread_cleanup_pop() function conforms to ISO/IEC 9945-1:1996 (``POSIX.1''). BSD October 25, 2014 BSD
