How does this code work...

I got the following code from parksie, that had a messagebox show the Windows Dir.
But I don't understand what the first line does:

The first line:

TCHAR pcBuf[MAX_PATH];

The entire code:

TCHAR pcBuf[MAX_PATH];
	GetWindowsDirectory(pcBuf, MAX_PATH);
	MessageBox(pcBuf, "Windows folder!", MB_OK);

TCHAR is a universal character type -- if you compile for ANSI or MBCS (multi-byte character set) then it resolves to char. If you compile for Unicode it resolves to wchar_t (a 2-byte type).

So, the first line:

TCHAR pcBuf[MAX_PATH];

This allocates an array of TCHAR with size MAX_PATH (a constant defined in the Windows header files, and I think it's 260).

Thank you! That helped!
