enums

[David Keppel]

When you have an enum of the form:

	enum light_t { ON, OFF, FIZZLING };

it can be nice to be able to print the members.  I've written a
(completely gross hack) program that scans a .c or .h and produces a
file with an extra .c tacked on the end (e.g., .c.c or .h.c) that
contains static initializers like:

	char *light_t_s[] = {
		"ON", "OFF", "FIZZLING", 0
	};

On newer compilers you can then get a printable string by saying
something like:

	for( light=ON; light <= FIZZLING; ++light ){
		printf( "light is %s..\n", light_t_s[light] );
	}

Unfortunately this won't work when you have particular values
assigned to an enumerted type ( FOO=-1, BAR=0, BORK=1 ).

If you're on the DARPA net you can anonymous ftp from

	% ftp june.cs.washington.edu
	login: anonymous
	passwd: <your user name goes here>
	cd pub
	get enum.c

Otherwise, send me e-mail and I'll send you a copy.

There's no man page, and the code isn't of sufficient quality to
post.  Please keep me informed of changes...
