The char keyword specifies an 8-bit data item.
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 keyword char identifies a data item that has 8 bits. To the MIDL compiler, a char is unsigned by default and is synonymous with unsigned char.
In this version of Microsoft RPC, the character translation tables that convert between ASCII and EBCDIC are built into the run-time libraries and cannot be changed by the user.
The char type is one of the base types of the interface definition language (IDL). The char type can appear as a type specifier in const declarations, typedef declarations, general declarations, and function declarators (as a function-return-type specifier and a parameter-type specifier). For the context in which type specifiers appear, see Interface Definition (IDL) File.
