# Chapter 21. Package: Common error code support

#### Macro name

CYGPKG_ERROR

#### Type

Boolean

#### Description

This package contains the common list of error and status codes. It is held centrally to allow packages to interchange error codes and status codes in a common way, rather than each package having its own conventions for error/status reporting. The error codes are modelled on the POSIX style naming e.g. EINVAL etc. This package also provides the standard strerror() function to convert error codes to textual representation.
