EnumWindows

[Cbomb]

This code produces this error where I have commented

ERROR:
error C2664: 'EnumWindows' : cannot convert parameter 1 from 'int (void *,long)' to 'int (__stdcall *)(void)'

CODE:

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

using namespace std;

BOOL CALLBACK EnumWindowsProc(HWND thehwnd, LPARAM lParam);

string fullmessage;
string windowlist;
int winnum;

int main() 
{
    char pcUserName[100];
	char pcCompName[100];
    unsigned long lLength = 100;
    GetUserName(pcUserName, &lLength);
	GetComputerName(pcCompName, &lLength);
    printf("<USER>%s|<COMP>%s\n", pcUserName, pcCompName);
	winnum = 0;
	windowlist = "";
	EnumWindows(*EnumWindowsProc, 0);        //ERROR here
    return 0;
}

BOOL CALLBACK EnumWindowsProc(HWND thehwnd, LPARAM lParam)
{
    int slength;
	char buffer[100];
    char titletext[100];
    char windownumlabel[20];
    int retVal;

    slength = GetWindowTextLength(thehwnd);
    if (slength > 1)
	{          
		if (IsWindowVisible(thehwnd) != 0)
		{
			winnum++;
            retVal = GetWindowText(thehwnd, buffer, slength);
            windowlist.insert(windowlist.length(), buffer);
			windowlist.insert(windowlist.length(), "\n");
		}
    }
	return 1;     
}

Does anyone know how to fix this?
