I am writing an application that needs a function that returns a pointer to a function (which returns an int). Can anyone send me an example of how to declare such a function? -- Randy R. Magnuson magnuson@skyler.mavd.honeywell.com (612-542-5052)

(MS-DOS and VAX/VMS) Yeah -- you can find the source in K&R2 (5.12) for a simpler similar program, and with a modest amount of work you should be able to fill in the gaps. Or, you could adapt the "cdecl" sources; there shouldn't be any real dependencies on UNIX in that program.

But Unix executables won't run on MS-DOS or VAX/VMS as far as I know. And programs in source code that have been tar'd or z'd or whatever require Unix-based utilities to unpack them.
