The reason changing the extension from .c to .cp made it work is the functions are now C++ functions, complete with mangled names. That's where you were running into trouble before. To inhibit the name mangling, put 'extern "C"' in front of the prototype, like so: extern "C" void *myFunc (int arg1, float arg2); // or extern "C" { void *myFunc (int arg1, float arg2); int *myFunc1 (int arg1, float arg2); // also a C function } Now, for the pointer conversion. Let me see if I understand what you're saying. You want to do something like this in C++? void *vPtr; char *cPtr; // assume pointers are initialized & what-not cPtr = vPtr; // or equivalent in a function call In other words, you want to put the contents of a void pointer into a char pointer? C++ lets you assign any pointer type to variable of type void *, but NOT the other way around; C++ considers such things "unsafe." Typecasting, however, works, as in (char *)vptr = cPtr; Joe
