I believe it's saying that the function has external linkage, but
doesn't seem to be used from within some other foo.c, so the external
linkage is unnecessary, in which case you should consider switching to
internal linkage (via the use of the "static" keyword).
If the error doesn't apply to your case (only checking one file at a
time, building a library, etc.), you should silence the warning. Most
lint programs need to be "tuned" to your specific needs.
FWIW, someone on comp.lang.c recently was complaining that lclint
complains about things it shouldn't, and doesn't complain about things
it should (not that lint is topical for c.l.c.)... I haven't had a
chance to evaluate it yet.
