Usually it's much more readable and helps to avoid not necessary indentation
to check parameters at the start of the function and return right away with
appropriate error code. Besides you are mixing tabs and spaces.

You marked pSrcFile parameter 'const' in D3DXAssembleShaderFromFileA declaration
but not in D3DXAssembleShaderFromFileW, any reason for that?
