I'm receiving an exit code 64 in our batch scheduler (BMC product control-m) executing a PERL script on UX-HP. Can you tell me where I can find a list of exit codes and their meaning. I'm assuming the exit code is from the Unix operating system not PERL.

10. Programming

Return or exit codes apart from 0 have a meaning?

The standard return code when everything goes right is 0, but what about using any other number something happened? Are there "ranges" depending on the kind of problem you want to express or is totally up to the programmer?

_exithandle

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.
