Run-Time Library Reference

The Microsoft run-time library provides routines for programming for the Microsoft Windows 98, Windows Me, Windows NT, Windows 2000, and Windows XP operating systems. These routines automate many common programming tasks that are not provided by the C and C++ languages.

Sample programs are included in the individual reference topics for most routines in the library.
