The only locale names you can count on finding on all operating systems
are these three standard ones:
This is the standard C locale. The attributes and behavior it provides
are specified in the ISO C standard. When your program starts up, it
initially uses this locale by default.
This is the standard POSIX locale. Currently, it is an alias for the
standard C locale.
The empty name says to select a locale based on environment variables.
See Locale Categories.
Defining and installing named locales is normally a responsibility of
the system administrator at your site (or the person who installed the
GNU C library). It is also possible for the user to create private
locales. All this will be discussed later when describing the tool to
If your program needs to use something other than the `C' locale,
it will be more portable if you use whatever locale the user specifies
with the environment, rather than trying to specify some non-standard
locale explicitly by name. Remember, different machines might have
different sets of locales installed.
