how to pass pointers to a function in C

What I want to do is to put DLLname where DLLnameHERE.dll is.

This is a piece of my code:

int ToLoadLibrary(char * DLLname) 
{

HINSTANCE hinstLib;
MYPROC ProcAdd;
BOOL fFreeResult, fRunTimeLinkSuccess = FALSE;

// Get a handle to our DLL module created in the previous example. Make sure you already copied the mydllpro.lib and mydllpro.dll to the appropriate folders...
hinstLib = LoadLibrary(L"DLLnameHERE.dll");

Thanks in advance.

The problem you run into is a Microsoft-specific one. The macro LoadLibrary expands, depending on preprocessor macros, either to the name of a function that accepts a char const* or a wchar_t const *. In your case, the call

hinstLib = LoadLibrary(L"DLLnameHERE.dll");

suggests that the latter is the case.

The easiest way around this problem is to use the name of the function that accepts char const * directly; it is LoadLibraryA:

hinstLib = LoadLibraryA(DLLname);

The mechanism is described in greater detail here in the MSDN.
