(C) Get root of drive

[Neo_Reloaded]

This function i made because i couldnt find a standard C or C++ function to get the root (like E:\) of the systems drive where windows is installed.

So my version uses the GetWindowsDirectory function to get which drive has windows installed like (E:\Windows\System32\), then strips the (\Windows\System32\) from it and returns to drive letter like this (E:\)

void driveRoot()
{
	char winRoot[100];
	short int x = 0;
	char driveRoot[4];

	GetSystemDirectory(winRoot,sizeof(winRoot));

	while(winRoot[x] != '\\')
	{
		driveRoot[x] = winRoot[x];
		x++;
	}
	driveRoot[x] = '\\';
	driveRoot[x+1] = NULL; // Add a NULL to end of string
	printf("%s", driveRoot);
}
