NAME

       stringprep - API function

SYNOPSIS

       #include <stringprep.h>

       int stringprep(char * in, size_t maxlen, Stringprep_profile_flags flags, const Stringprep_profile * profile);

ARGUMENTS

       char * in   input/ouput array with string to prepare.

       size_t maxlen
		   maximum length of input/output array.

       Stringprep_profile_flags flags
		   a Stringprep_profile_flags value, or 0.

       const Stringprep_profile * profile
		   pointer to Stringprep_profile to use.

DESCRIPTION

       Prepare the input zero terminated UTF-8 string according to the stringprep profile, and write back the result to the input string.

       Note that you must convert strings entered in the systems locale into UTF-8 before using this function, see stringprep_locale_to_utf8().

       Since  the  stringprep operation can expand the string, maxlen indicate how large the buffer holding the string is.  This function will not
       read or write to characters outside that size.

       The flags are one of Stringprep_profile_flags values, or 0.

       The profile contain the Stringprep_profile instructions to perform.  Your application  can  define  new	profiles,  possibly  re-using  the
       generic stringprep tables that always will be part of the library, or use one of the currently supported profiles.

RETURN VALUE

       Returns STRINGPREP_OK iff successful, or an error code.
