Are you aware that lPitch is a (signed) LONG in the original DDSURFACEDESC structure? Honestly I have no idea why, and I have never seen an app that passes a negative pitch, but it might lead to obscure bugs if it is not checked.

MSDN says that dwPitchOrLinearSize is DWORD in the DDS_HEADER. Also, the same definition is used in a D3D sample. On the other hand, we can define it as LONG to be safe.

Nah, no need in that case. But I recommend to write tests for invalid pitches
