NAME

       stringprep_locale_charset - API function

SYNOPSIS

       #include <stringprep.h>

       const char * stringprep_locale_charset( void);

ARGUMENTS

        void

DESCRIPTION

       Enumerated  return  codes  of  the  TLD  checking functions.  The value 0 is guaranteed to
       always correspond to success.

       Find out current locale charset.  The function respect the CHARSET  environment  variable,
       but  typically uses nl_langinfo(CODESET) when it is supported.  It fall back on "ASCII" if
       CHARSET isn't set and nl_langinfo isn't supported or return anything.

       Note that this function return the application's locale's preferred charset  (or  thread's
       locale's  preferred charset, if your system support thread-specific locales).  It does not
       return what the system may be using.  Thus, if you receive data from external sources  you
       cannot  in  general  use  this  function  to  guess  what  charset  it is encoded in.  Use
       stringprep_convert from the external representation into  the  charset  returned  by  this
       function, to have data in the locale encoding.

       Return  value:  Return the character set used by the current locale.  It will never return
       NULL, but use "ASCII" as a fallback.
