public

The [public] attribute includes an alias declared with the typedef keyword in the type library.

typedef [public] data-type identifier;

Parameters

data-type

The data type that the identifier will be an alias for.

identifier

Another name by which data-type will be known in the software.

Remarks

By default, an alias that is declared with typedef and has no other attributes is treated as a #define and is not included in the type library. Using the [public] attribute ensures that the alias becomes part of the type library.

Note  The MIDL compiler requires that you explicitly apply the [public] attribute to each typedef that you want public. This is in contrast to MKTYPLIB, which treats as public, every typedef inside of a public interface block.

Example

typedef [public] long MEMBERID;
