cc -mt [ flag... ] file... -lpthread [ library... ] #include <pthread.h> void pthread_cleanup_pop(int execute);
The pthread_cleanup_pop() function removes the cleanup handler routine at the top of the cancellation cleanup stack of the calling thread and executes it if execute is non-zero.
When the thread calls pthread_cleanup_pop() with a non-zero execute argument, the argument at the top of the stack is popped and executed. An argument of 0 pops the handler without executing it.
The pthread_cleanup_push(3C) and pthread_cleanup_pop() functions can be implemented as macros. The application must ensure that they appear as statements, and in pairs within the same lexical scope (that is, the pthread_cleanup_push() macro can be thought to expand to a token list whose first token is '{' with pthread_cleanup_pop() expanding to a token list whose last token is the corresponding '}').
The effect of the use of return, break, continue, and goto to prematurely leave a code block described by a pair of pthread_cleanup_push() and pthread_cleanup_pop() function calls is undefined.
Using longjmp() or siglongjmp() to jump into or out of a push/pop pair can result in either the matching push or the matching pop statement not getting executed.
The pthread_cleanup_pop() function returns no value.
No errors are defined.
The pthread_cleanup_pop() function will not return an error code of EINTR.
