Calling Conventions: Overview

|  How Do I |  Details

The Visual C/C++ compiler provides several ways to call internal and external functions. Understanding these different approaches can help you debug your program and link your code with assembly-language routines.

The Details articles on this subject explain the differences between the calling conventions, how arguments are passed, and how values are returned by functions. They also discuss naked function calls, an advanced feature that enables you to write your own prolog and epilog code.
