According to Jim Roland:

So the convention to access a system call or part of the C Library is to declare a function with same parameters and return data-type and put a C; at the end of it?

Yes.

Seems too easy! :)

Okay, if you prefer something more difficult: The `C' directive is only to declare functions that are lowercase only. If the C declaration is in mixed case, for instance

void MyCFunction ( int foo, long bar, long long baz );

write

Procedure MyCFunction ( foo: Integer; bar: MedInt; baz: LongInt ); AsmName 'MyCFunction';

(* For more about `MedInt' and friends, see `info -f gpc -n "Integer types"'. This requires something more recent than gpc-2.0; see
