There need not be :)

Every one of the BGI features in the pascal version of the BGI has the
same name in the c version.  However you will need to prototypye all of
them to be able to link with them from a pascal program due to the way GPC
mangles identifiers.

so for example:

#include nameofbgiheader.h
procedure bgifeature(args...);external;c;

You can mix caps on the identifier and there will be no problem.

I suggest making your own header file (or Unit) that has prototypes for
all the features that you use.  If you actually sit down and write do it
for every function/procedure, I'm sure that there are many people who
would appreciate you posting it to DJ for inclusion in his achives. :)
