       If the locale's values for p_cs_precedes and n_cs_precedes do not match, the value of nl_langinfo(CRNCYSTR) is unspecified.

       The <langinfo.h> header declares the following as a function:

       char *nl_langinfo(nl_item);

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

USAGE

       Wherever possible, users are advised to use functions compatible with those in the ISO C standard to access items of langinfo data. In par-
       ticular, the strftime(3C) function should be used to access date and time information defined in category LC_TIME. The localeconv(3C) func-
       tion should be used to access information corresponding to RADIXCHAR, THOUSEP, and CRNCYSTR.
