If you have Masm 5.1 you should have the documentation for mixed language
programming which will tell you how to call an ASM program from C.
If you use the new segemnt directives which I know will work with Microsoft C.
You would go DOSSEG
.MODEL SMALL,C          ;depending on the model required
                        ;the C sets up the stack for proper returns
.CODE
PUBLIC  hello
hello   PROC
        ...
        code
        ret
hello   ENDP

If yopu do not use the masm simplified directive you have save the bp register
on the stack and it depends on the model you use.
