[Dev-C++] Scope of a type definition...

[DXFX <vin...@ed...>]

I was editing the source file below to make it work with the MinGW compiler. However, there's this error that always appears and I don't know how to revise the statement. The line with the comment //~+ refers to what the compiler says is the problem. Please anyone help in revising that line(s).

// file lsmultimon.h:

}

void TestRun(MONITORENUMPROC param) {
    cout << "Compiled";
}

BOOL CALLBACK TProc(HMONITOR hm, HDC hdc, LPRECT lpr, LPARAM lp){
}




The following where the errors.

8 main.cpp
 `MONITORENUMPROC' was not declared in this scope

8 main.cpp
 variable or field `TestRun' declared void

12 main.cpp
 `TestRun' cannot be used as a function

15 main.cpp
 `MONITORENUMPROC' was not declared in this scope

15 main.cpp
 parse error before `)'

8 main.cpp
 previous non-function declaration `int TestRun'

15 main.cpp
 conflicts with function declaration `void TestRun(...)'



Whats confusing me is that the type MONITORENUMPROC has been already declared in the header file. (correct me in that If I am wrong)

Does anyone know what the compiler is telling me?

Thanks in advance...

PS

lsmultimon.h is part of LiteStep Source code. I'm revising it to make it work with MinGW. Please Help ME!
