Can anyone help me with a DLL?

I have written a DLL which is called upon by Visual Basic. The cod which it is having problems with is:

Code:

---


NOMANGLE int CCONV readfile(int *lparray, int pixelbit, long head, long width, long height, LPSTR fname)

---

Alledgedly, this code has three errors:
C:\Uni\C\Source Code\readanddraw.c(19) : error C2061: syntax error : identifier 'readfile'
C:\Uni\C\Source Code\readanddraw.c(19) : error C2059: syntax error : ';'
C:\Uni\C\Source Code\readanddraw.c(19) : error C2059: syntax error : 'type'

I can't understand any of these errors and why they would possibly exist. Could anyone help?

Thanks!

BTW, that line of code I have posted is line 19.

To follow on....the NOMANGLE & CCONV symbols are not familiar to me........from what I can guess they are there to stop C++ function mangling....is this correct?

If so, then your compiler will have a specific method to do this...

With MSVC++ I would do the following...

Code:

---

#define DllImport extern "C" __declspec (dllimport)




DllImport int MyReadFile(int *lparray,
                        int pixelbit,
                        long head,
                        long width,
                        long height,
                        LPSTR fname);

---

That would normally allow me to import without problems....but then I cant guarantee as every dll I have ever written has been in C++ :)
