.LP
If the locale's values for \fBp_cs_precedes\fR and \fBn_cs_precedes\fR do not
match, the value of \fBnl_langinfo(CRNCYSTR)\fR is unspecified.
.sp
.LP
The <\fBlanginfo.h\fR> header declares the following as a function:
.sp
.in +2
.nf
char *nl_langinfo(nl_item);
.fi
.in -2

.sp
.LP
Inclusion of <\fBlanginfo.h\fR> header may also make visible all symbols from
<\fBnl_types.h\fR>.
.SH USAGE
.sp
.LP
Wherever possible, users are advised to use functions compatible with those in
the ISO C standard to access items of \fBlanginfo\fR data. In particular, the
\fBstrftime\fR(3C) function should be used to access date and time information
defined in category \fBLC_TIME\fR. The \fBlocaleconv\fR(3C) function should be
used to access information corresponding to \fBRADIXCHAR\fR, \fBTHOUSEP\fR, and
\fBCRNCYSTR\fR.
