Synopsis
#include <stdlib.h>
void exit(int status);
Status
Partially implemented
Conformance
IEEE Std 1003.1-2017
Description
The value of status may be 0, EXIT_SUCCESS, EXIT_FAILURE, or any other value, though only the least significant 8 bits
(that is, (_status_ & 0377)) shall be available from wait() and waitpid(). The full value shall be available from waitid() and in the siginfo_t passed to a signal handler for SIGCHLD.
The exit() function shall first call all functions registered by atexit(),
in the reverse order of their registration, except that a function is called after any previously registered functions that had
already been called at the time it was registered. Each function is called as many times as it was registered. If, during the call
to any such function, a call to the longjmp() function is made that would terminate
the call to the registered function, the behavior is undefined.
If a function registered by a call to atexit() fails to return, the remaining
registered functions shall not be called and the rest of the exit() processing shall not be completed. If exit() is
called more than once, the behavior is undefined.
The exit() function shall then flush all open streams with unwritten buffered data and close all open streams. Finally,
the process shall be terminated with the same consequences as described in Consequences of Process Termination.
Return value
The exit() function does not return.
