setjmp.h
A type that is an array used by setjmp and longjmp to save and
restore the program environment.
<setjmp.h>
typedef int jmp_buf[_NSETJMP];
_NSETJMP is defined as 16 + 2 that represents 16 registers and a
32-bit return address.
A macro that saves the current state of the program for later use by
longjmp.
<setjmp.h>
#define setjmp(jmp_buf env)
env variable where environment is stored
If the return is from a direct call, setjmp returns zero. If the return is
from a call to longjmp, setjmp returns a non-zero value.
Note: If the argument val from longjmp is 0, setjmp returns 1.
See longjmp.
A function that restores the environment saved by setjmp.
<setjmp.h>
void longjmp(jmp_buf env, int val);
env variable where environment is stored
val value to be returned to setjmp call.
The value parameter val should be non-zero. If longjmp is invoked
from a nested signal handler (that is, invoked as a result of a signal
raised during the handling of another signal), the behavior is undefined.
consists of a type, a macro and a function that allow control
