Routine Description:
    This function checks if the given snapshot makes sense. It covers only
    conditionally required entries and printing commands since other
    statically required entries are already covered by snapshot functions.

Arguments:
    pInfoHdr: pointer to INFOHEADER structure.

Return Value:
    TRUE if the semantics is correct. Otherwise, FALSE.
