CRNCYSTR LC_MONETARY local currency symbol, preceded by '-' if the symbol should appear before the value, '+' if the symbol should appear after the value, or '.' if the symbol should replace the radix character

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>.

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(3C) function should be used to access date and time information defined in category LC_TIME. The localeconv(3C) function should be used to access information corresponding to RADIXCHAR, THOUSEP, and CRNCYSTR.
