Standard C Library (libc, -lc) SYNOPSIS
#include <stdlib.h> _Noreturn void quick_exit(int status); DESCRIPTION
The quick_exit() function exits the program quickly calling any cleanup functions registered with at_quick_exit(3) but not any C++ destruc- tors or cleanup code registered with atexit(3). RETURN VALUES
The quick_exit() function does not return. SEE ALSO
at_quick_exit(3), exit(3) STANDARDS
The quick_exit() function conforms to ISO/IEC 9899:2011 (``ISO C11''). BSD

EXIT(3) 						   BSD Library Functions Manual 						   EXIT(3)

exit, _Exit -- perform normal program termination LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <stdlib.h> void exit(int status); void _Exit(int status); DESCRIPTION
The exit() and _Exit() functions terminate a process. Before termination, exit() performs the following functions in the order listed: 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. The _Exit() function terminates without calling the functions registered with the atexit(3) function, and may or may not perform the other actions listed. Both functions make the low-order eight bits of the status argument available to a parent process which has called a wait(2)-family function. The C Standard (ISO/IEC 9899:1999 (``ISO C99'')) defines the values 0, EXIT_SUCCESS, and EXIT_FAILURE as possible values of status. Cooper- ating processes may use other values; in a program which might be called by a mail transfer agent, the values described in sysexits(3) may be used to provide more information to the parent process. Note that exit() does nothing to prevent bottomless recursion should a function registered using atexit(3) itself call exit(). Such func- tions must call _Exit() instead (although this has other effects as well which may not be desired). RETURN VALUES
The exit() and _Exit() functions never return. SEE ALSO
_exit(2), wait(2), atexit(3), intro(3), sysexits(3), tmpfile(3) STANDARDS
The exit() and _Exit() functions conform to ISO/IEC 9899:1999 (``ISO C99''). BSD
