.TH NL_LANGINFO 3C "Jun 24, 2014"
.SH NAME
nl_langinfo, nl_langinfo_l \- language information
.SH SYNOPSIS
.LP
.nf
#include <langinfo.h>

\fBchar *\fR\fBnl_langinfo\fR(\fBnl_item\fR \fIitem\fR);
.fi
.LP
.nf
\fBchar *\fR\fBnl_langinfo_l\fR(\fBnl_item\fR \fIitem\fR, \fBlocale_t\fR \fIloc\fR);
.fi
.SH DESCRIPTION
.LP
The \fBnl_langinfo()\fR function returns a pointer to a null-terminated string
containing information relevant to a particular language or cultural area
defined in the programs locale. The manifest constant names and values of
\fIitem\fR are defined by <\fBlanginfo.h\fR>. For example:
.IP
\fBnl_langinfo\fR(\fBABDAY_1\fR);
.LP
would return a pointer to the string "\fBDim\fR" if the identified language was
French and a French locale was correctly installed; or "\fBSun\fR" if the
identified language was English.
.LP
The function \fBnl_langinfo_l()\fR behaves identically to \fBnl_langinfo()\fR,
except instead of acting in the current locale, it instead acts in the locale
specified by \fIloc\fR.
.SH RETURN VALUES
.LP
If the locale has not been set or is invalid, or if  data for a
supported language is either not available, or if \fIitem\fR is not defined
therein, then these functions return a pointer to the corresponding string
in the C locale. In all locales, they return a pointer to an
empty string if \fIitem\fR contains an invalid setting.
.SH ATTRIBUTES
.LP
