msvc - cant find function

The problem comes when i try to compile using the function: CreateFileForMapping() So where is this function defined ? I currently include: windows.h Winbase.h // msdn say that CreateFileForMapping is defined here stdio.h any help would be ok

Im just testing out mmapping so here is the entire source as it is:


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

using namespace std;


void main()
{
	HANDLE hFile = NULL;
	hFile = CreateFileForMapping( "test_file.txt", GENERIC_WRITE | GENERIC_READ,
								  0, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL,
								  FILE_FLAG_RANDOM_ACCESS );
	if( hFile )
		cout << "CreateFileForMapping - ok" << endl;
	else
		return;


	hFile = CreateFileMapping( INVALID_HANDLE_VALUE, NULL, PAGE_READWRITE, 0,5, "test.txt" );

	if( hFile )
		cout << "CreateFileMapping - ok" << endl;
	else
		return;

	char* file = (char*)MapViewOfFile( hFile, FILE_MAP_WRITE, 0, 0, 0 );
	if( file == NULL )
	{
		cout << "MapViewOfFile - fail" << endl;
		return;
	}

	cout << "file: " << file << endl;

	UnmapViewOfFile( file );
}
