p When .Fa cleanup_routine is called, it is passed .Fa arg as its only argument.
p The .Fn 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 .Xr pthread_cleanup_pop 3 in the same lexical scope. .Sh RETURN VALUES The .Fn pthread_cleanup_push function does not return any value. .Sh ERRORS None .Sh SEE ALSO .Xr pthread_cleanup_pop 3 , .Xr pthread_exit 3 .Sh STANDARDS The .Fn pthread_cleanup_push function conforms to .St -p1003.1-96 .
