What I'm wondering about are things like, should library functions print
error messages, if so, in what cases; or should they only pass on any
errors they get, if so, how; is there any time when they should abort
a program, etc.?

I strongly believe that library routines should ONLY return error
codes. The error codes should be universal across all routines (ala
com_err style). Applications should be able to deal with error codes
in their manner. The library should never force an screen display and
especially should never cause a program abort.
