The exit value of a program returning to the shell on unixoid systems is
typically 0 for success, and non-0 (such as 1) for failure. For vms it is
odd (1,3,5...) for success, even (0,2,4...) for failure.
The exit value of a program returning to the shell on unixoid systems
is typically 0 for success, and non-0 (such as 1) for failure. This is
not always the case on other systems.
This holds from the point of view of the "shell" (in quotes because vms has a
different dispatch model that is not explained further here).
From the point of view of the program, nowadays stdlib.h on both type of
systems provides macros `EXIT_SUCCESS' and `EXIT_FAILURE' that should DTRT.
NB: The numerical values of these macros DO NOT need to fulfill the exit
value requirements outlined in the first paragraph! That is the job of the
From the point of view of the program stdlib.h provides macros
`EXIT_SUCCESS' and `EXIT_FAILURE' that should DTRT. N.B. The
numerical values of these macros DO NOT need to fulfill the exit value
requirements outlined in the first paragraph! That is the job of the
`exit' function. Thus, this kind of construct shows misunderstanding:
#ifdef VMS
#ifdef WEIRD_OS
exit (1);
#else
exit (0);
#endif
Values aside from EXIT_SUCCESS and EXIT_FAILURE are tricky.
Values aside from EXIT_SUCCESS and EXIT_FAILURE are tricky, but can be
used to indicate finer gradations of failure. If this is the only
information available to the caller, clamping such values to
EXIT_FAILURE loses information. If there are other ways to indicate
the problem to the caller (such as a message to stderr) it may be ok
to clamp. In all cases, it is the relationship between the program
and its caller that must be examined.
