NAME

       stringprep_4zi - API function


SYNOPSIS

       #include <stringprep.h>

       stringprep_4zi(3) * ucs4, size_t maxucs4len,
       Stringprep_profile_flags flags, const Stringprep_profile * profile);


ARGUMENTS

       uint32_t * ucs4
                   input/output array with zero terminated string to prepare.

       size_t maxucs4len
                   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 UCS-4 string according to the
       stringprep profile, and write back the result to the input string.

       Since the stringprep operation can expand the string,  maxucs4len
       indicate how large the buffer holding the string is.  This function will
       not read or write to code points 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 Stringprep_rc
       error code.
