/////////////////////////////// CMem Class /////////////////////////////////

#ifdef DESCRIPTION

	This class is used for allocating a block of memory which is
	automatically freed when the object goes out of scope. It uses
	LocalAlloc and therefore doesn't affect the heap.

public:
	PBYTE pb;
	PSTR  psz; // identical to pb, used for casting convenience

	CMem(int size);
	~CMem(void);

	operator void*() { return (void*) pb; };
	operator PCSTR() { return (PCSTR) psz; };
	operator PSTR()  { return psz; };
	operator PBYTE() { return pb; };
