As the last line of the Sun man-page for "lint" reads: ...it is still useful to produce stripped down lint library source files and to use them to generate lint libraries. However, there are no flags (or combinations of same) which seem to result in the production of said "stripped down lint library source files". Does anyone out there have any suggestions (besides the obvious -- "make it yourself by hand") as to how to go about creating these? One of the people in the group is currently writing a simple little program which will pull out all #includes and function definitions, but if somebody out there already has some s/w which creates lint source files, we'd really like to hear about it. Many thanks, and please respond via email. doug -- # ____ Internet: elias@theory.tn.cornell.edu # dr _|_)oug USmail: Adv. Comp. Res.

From the lint manual page:
-Clibrary
Create a lint library with the name llib-llibrary.ln.
Also, -i will generate a .ln file with just the routines and the call
lines.

Sigh. Doing it by hand is usually required. You pick up cproto off of one of the archives and modify it trivially to produce a 90% solution. You still have to pick up things like int errno; /* declare errno because it is an exported global */ and cproto won't help you there. The other thing you can do is just use the real source. I discourage this within Sun because we like to ship the source to the lint libs; programmers actually grep through them to see which way the args go. This means that you should say bcopy(src, dest, len) not bcopy(p1, p2, i) Using cproto usually works for this because the source is usually good about meaningful names. --- Larry McVoy, Sun Microsystems (415) 336-7627 ...!sun!lm or lm@sun.com

Nice try, but a ".ln" file is *NOT* a "stripped down lint library source file", it's a *binary* "lint" library file. As Larry McVoy (who was recently in hand-to-hand combat with "lint" libraries) notes, having the stripped-down source files are handy, because when "lint" complains about a parameter mismatch between line XXX of YYY.c and line NNN of llib-ZZZ, you can go look at line NNN of llib-ZZZ (that being the stripped-down "lint" library source file) and see what parameters the routine expects.
