QUERYLOCALE(3)

NAME
querylocale - Look up the locale name or version for a specified category

LIBRARY
libc

SYNOPSIS
#include <locale.h>
const char *
querylocale(int mask, locale_t locale);

DESCRIPTION
Returns the name or version of the locale for the category specified by mask. The possible values for the mask are the same as those in newlocale(3), when requesting the locale name. Specify the bitwise OR of LC_VERSION_MASK and another mask value to request a version string. Version strings can be compared to detect changes to the locale's definition. The structure of the version string is unspecified. Currently, version information is only available for LC_COLLATE_MASK, and an empty string is returned for other categories. If more than one bit in the mask is set, not counting LC_VERSION_MASK, the returned value is undefined.

HISTORY
