# querylocale(3)

Get locale name for a specified category

## NAME

**querylocale** – Get locale name for a specified category

## SYNOPSIS

**#include \<xlocale.h\>**

*const* *char* *\**\

**querylocale**(*int mask*, *locale\_t loc*);

## DESCRIPTION

Returns the name of the locale for the category specified by *mask*. The *mask* is scanned starting at the least significant bit, until the first set bit is found. This happens to scan the categories alphabetically, not  including LC\_ALL\_MASK, but it is best to specify one category at a time. The available categories are documented in [xlocale(3)](/xlocale/3.md) and [newlocale(3)](/newlocale/3.md).
