Documenting a set of functions with -man

[Anton Shepelev]

Hello, all

What is the covenstional way of documenting a set of C
functions with -man?  Have you any recommendations or
examples about typesetting function declaraions, their
return types and aruguments in a classic man-page?  The .SY
macro does not seem to work well for C, because its function
declarations start with the return type.
