Data and Language Features

The Microsoft Interface Definition Language (MIDL) provides the set of features that extend the C programming language to support remote procedure calls. MIDL is not a variation of C; it is a strongly typed formal language through which you can control the data transmitted over a network. MIDL is designed so that developers familiar with C can learn it quickly.

This topic discusses three language features:

• Strong Typing
• Directional (Parameter) Attributes
• Data Representation
