stringprep_locale_charset(3)        libidn        stringprep_locale_charset(3)


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.
