So often MS-DOS questions are posted in comp.lang.c, it's novel to see a
C question in comp.os.msdos.programmer.

I don't know what you mean by "a #define would be nice"; typedefs are
the way to go for this.

The general principle if a typedef is to write a normal declaration that
looks the way you want, stick the word _typedef_ in front of it, and the
"variable" is the name of the new type.  Also for function pointers I
find it easiest to define a type for the function not the pointer.

Therefore:
     typedef int LPIFUNC(LPWORD);

A pointer to such a function would be 
     LPIFUNC *funcptr;
either independently as a variable or as a structure member or as a
function argument.
