Usually that's the case. However, depending on the what parameters need to be passed to the function, it may be difficult or even impossible to implement in VFP. For example, the WNetEnumResource function in MPR.DLL is difficult. People like Christof Lange and Ed Rauh have made it easier with classes to abstract the memory managment but it still isn't for the lay person. The EnumWindows function in User32.DLL is implossible to implement in VFP only because it makes use of a callback function. Because of VFP's memory management, callback function pointers are not available. People have written C/C++ FLLs to augment VFP but that is not VFP.

So saying all that, without knowing the contents of the include file and the declare statement, I can't give you a definitive answer.
