    ‘UInt16’ does not name a type

    Hello folks,

    I have a little problem. I use SDL to create some graphics and in this library there are some properties/function who has a Uint16 return type. so to catch these values i created a function of the type Uint16. but it gives me this error:

    ‘UInt16’ does not name a type
    is this type a general supperted type, or is it created by a typedef? of do i need to include some file?

    Thanks you helping,


    Sorry guys,

    I looked into my C++ book at the list of all variable types and it turn out that: uint16 is a short term for Unsigned int (16 bits large)

    Sorry for this not needed thread.

    No, in fact, uint16 is not a standard type.
    It must be defined somewhere in a header which you are presumably including.
    Also, unsigned short is not guaranteed to be 16 bits. If you need a type of exactly 16 bits, I recommend you take a look at boost's cstdint.hpp implementation.

    Outside of your DOS world, your header file is meaningless.
