sigsetjmp() -- General Function (libc)

Save machine state and signal mask for non-local jump
#include <setjmp.h>
int sigsetjmp(environ, savemask)
sigjmp_buf environ;
int savemask;

sigsetjmp() performs the same  action as the function setjmp(), except that
if the value of savemask is not zero, it saves the process's signal mask as
well as the machine state into the array to which environ points.
