u_int8_t, not SANE_Byte :-) > SANE_Char is (according to the standard) used for a textual character, > which may or may not be a byte in the future. SANE_Byte is a byte. SANE_Byte is a data type that can carry AT LEAST a byte. Theoretically, it may be bigger. > Although, technically SANE_Byte could be bigger than a byte; it just has > to be able to hold a byte. How about "uint8_t"? It's standard, no? I should read to the end first :-) It won't work this way, for other reasons. You don't know the size of e.g. SANE_String (pointer) or SANE_Word so if you add some new members, you don't know, to which value 32 must be decreased. SANE_Int could be 4 bytes, or 8. Or maybe something different? So probably the way to go is something like: SANE_String reserved1, reserved2, reserved3; SANE_Word reserved1, reserved2, reserved3; Or similar. Bye, Henning
