Provides information on C++ mixed-language calling conventions.

This section describes C++ mixed-language calling conventions.

You can call routines written in other languages, and vice versa. When you mix languages, you have to deal with two important issues: identifiers and parameter passing.

By default, the compiler saves all global identifiers in their original case (lower, upper, or mixed) with an underscore "_" prepended to the front of the identifier. To remove the default, you can use the -u command-line option.

Note: The section Linkage tells how to use extern, which allows C names to be referenced from a C++ program.
