завершить процесс (terminate a process)
Пролог (Prolog)
This manual page is part of the POSIX Programmer's Manual. The
Linux implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior),
or the interface may not be implemented on Linux.
Имя (Name)
exit — terminate a process
Синопсис (Synopsis)
#include <stdlib.h>
void exit(int status);
Описание (Description)
The functionality described on this reference page is aligned
with the ISO C standard. Any conflict between the requirements
described here and the ISO C standard is unintentional. This
volume of POSIX.1‐2017 defers to the ISO C standard.
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.
