exit(3) User Contributed Perl Documentation exit(3)NAME
Tk::exit - End the application
SYNOPSIS
use Tk qw(exit);
...
B<exit>?(I<returnCode>)?;
DESCRIPTION
Terminate the process, returning returnCode to the system as the exit status. If returnCode isn't specified then it defaults to 0.
If calling "exit" from code invoked via a Tk callback then this Tk version of "exit" cleans up more reliably than using the perl "exit".
CAVEATS
Using "exit" from a forked process will terminate both the child process and the parent process. As "Tk::exit" is imported by default one
should use "CORE::exit" in the forked process instead.
KEYWORDS
exit, process

exit(3C) Standard C Library Functions exit(3C)NAME
exit, _exithandle - terminate process
SYNOPSIS
#include <stdlib.h>
void exit(int status);
void _exithandle(void);
DESCRIPTION
The exit() function terminates a process by calling first _exithandle() and then _exit() (see exit(2)).
The _exithandle() function calls any functions registered through the atexit(3C) function in the reverse order of their registration. This
action includes executing all finalization code from the .fini sections of all objects that are part of the process.
The _exithandle() function is intended for use only with _exit(), and allows for specialized processing such as dldump(3C) to be performed.
Normal process execution should not be continued after a call to _exithandle() has occurred, as internal data structures may have been torn
down due to atexit() or .fini processing.
The symbols EXIT_SUCCESS and EXIT_FAILURE are defined in the header <stdlib.h> and may be used as the value of status to indicate success-
ful or unsuccessful termination, respectively.
