The part of DIB (Device-Independent Bitmap), that contains pixel data, can be too large for managing it via VFP strings. For that reason the GlobalAlloc/GlobalFree combination is used to allocate/release memory for this buffer.
The WriteFile function is declared in two different ways: one for strings and another for pointers.
