EXIT(3) OpenBSD Programmer's Manual EXIT(3) NAME exit - perform normal program termination SYNOPSIS #include <stdlib.h> void exit(int status); DESCRIPTION The exit() function terminates a process. Before termination it performs the following functions in the order list- ed: 1. Call the functions registered with the atexit(3) function, in the reverse order of their registration. 2. Flush all open output streams. 3. Close all open streams. 4. Unlink all files created with the tmpfile(3) function. Following this, exit() calls _exit(2). Note that typically _exit(2) only passes the lower 8 bits of status on to the parent, thus negative values have less meaning. RETURN VALUES The exit() function never returns. SEE ALSO _exit(2), atexit(3), intro(3), sysexits(3), tmpfile(3) STANDARDS The exit() function conforms to ANSI X3.159-1989 (``ANSI C''). OpenBSD 3.5 June 29, 1991 1
