siglongjmp() -- General Function (libc) Perform a non-local goto and restore signal mask #include <setjmp.h> void siglongjmp(environ, value) sigjmp_buf environ; int val; siglongjmp() behaves like the function longjmp(), except that it also restores the signal mask. environ points to an array of type sigjmp_buf, which is declared in header file setjmp.h. It must have been initialized by a call to sigsetjmp(). value is the integer value to be returned to the function that called sigsetjmp().
