exit(3) Library Functions Manual exit(3)
Name
exit - terminate a process after flushing any pending output
Syntax
void exit(status)
int status;
int atexit(func)
void (*func)();
Description
The function terminates a process after calling the Standard I/O library function, _cleanup, to flush any buffered output. The function
never returns.
The function registers a function to be called (without arguments) at normal program termination; functions are called in the reverse order
of their registration (that is, most recent first). If a function is registered more than once, it will be called more than once.
Return Values
The function returns zero if the registration succeeds, or -1 if the function pointer is null or if too many functions are registered.
