Explicit Linking Problem

[lexicon]

Hello;
I am trying to understand the concept of "Explicit Linking" but the following code gives the error error C2365: 'GetLogicalDrives' : redefinition; previous definition was 'function'
Other API functions such as FindFirstVolume, FindNextVolume, FindVolumeClose etc works properly.
Any ideas ?

#include <windows.h>
#include <stdio.h>

DWORD (WINAPI *GetLogicalDrives) (VOID);
int main()
{
	// Load the dll
	
	HMODULE hmod;
	if((hmod = LoadLibrary(TEXT("Kernel32.dll"))))
	{
		if((GetLogicalDrives = (DWORD (WINAPI*)(VOID))GetProcAddress(hmod,"GetLogicalDrives")))
		{
			DWORD drivesId = GetLogicalDrives();			
		}
	}
	
	return 0;
}
