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
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.
