.SH Description
.NXR "nl_langinfo subroutine"
The function
.PN nl_langinfo
returns a pointer to a null-terminated string containing information relevant 
to a particular language or cultural area. The language is identified by the

.PN <langinfo.h> .
.PP

would return a pointer to the string representing the abbreviated name for
the first day of the week, as defined by
.PN setlocale
category
.PN LC_TIME :

If the
.PN setlocale
category has not been called successfully,
.PN langinfo
data for a supported language is not available, or 
.PN item
is not defined, then
.PN nl_langinfo
returns a pointer to an empty (null) string.
