Internal CRT globals and functions

Artikel
02/03/2023

The C runtime (CRT) library contains functions and global variables that are used only to support the public library interface. Some of them are exposed in public headers as implementation details. Although these functions and global variables are accessible through public exports, they're not intended for use by your code. We recommend that you change any code that uses these functions and variables to use public library equivalents instead. These functions may change from version to version. They're listed here to help you identify them. Links are provided when other documentation exists, but in general, these implementation details aren't documented.

Internal CRT globals and value macros

These global variables and macro definitions are used to implement the CRT.
