The following shall be declared as a function and may also be defined as a macro. A function prototype shall be provided.


char *nl_langinfo(nl_item);

Inclusion of the <langinfo.h> header may also make visible all symbols from <nl_types.h>.

The following sections are informative.

APPLICATION USAGE

Wherever possible, users are advised to use functions compatible with those in the ISO C standard to access items of langinfo data. In particular, the strftime() function should be used to access date and time information defined in category LC_TIME . The localeconv() function should be used to access information corresponding to RADIXCHAR, THOUSEP, and CRNCYSTR.

RATIONALE

None.

FUTURE DIRECTIONS

None.
