The langinfo.h header file contains the declaration for the nl_langinfo() function. The header file also defines the macros that, in turn, define constants used to identify the information queried by nl_langinfo() in the current locale. The following macros are defined:

The YESSTR and NOSTR constants are kept for historical reasons. They were part of the Legacy Feature in Single UNIX Specification, Version 2. They have been withdrawn and are not supported as part of Single UNIX Specification, Version 3.
If it is necessary to continue using these constants in an application written for Single UNIX Specification, Version 3, define the feature test macro _UNIX03_WITHDRAWN before including any standard system headers. The macro exposes all interfaces and symbols removed in Single UNIX Specification, Version 3.
