This is a case of RTFM, I'd say.  Both my 5.01 MASM and my 5.x C have
a manual, or section of a manual (they're both the exact same pages, just
one is a stand-alone manual, and the other is a section of a binder) called
"Mixed Language Programming Guide".  Section 6.6 of that guide is titled
"Calling High-Level Languages from Assembly".  The first paragraph is:

 High-level language routines assume that certain initialization code has
 previously been executed; you can ensure that the proper initialization is
 performed by starting in a high-level language module, and then calling an
 assembly procedure.  THE ASSEMBLY PROCEDURE CAN THEN CALL HIGH-LEVEL
 LANGUAGE ROUTINES AS NEEDED...

It then goes on to explain four guidelines to be observed in making the call.
