The small keyword designates an 8-bit integer number.
Specifies a valid MIDL identifier. Valid MIDL identifiers consist of up to 31 alphanumeric and/or underscore characters and must start with an alphabetic or underscore character.
The small keyword can be preceded by either the keyword signed or the keyword unsigned. The int keyword is optional and can be omitted. To the MIDL compiler, a small integer is signed by default and is synonymous with signed small int.
The small integer type is one of the base types of the IDL language. The small integer type can appear as a type specifier in const declarations, typedef declarations, general declarations, and function declarators (as a function return–type specifier and as a parameter-type specifier). For the context in which type specifiers appear, see Interface Definition (IDL) File.
