stringprep_4i - API function
#include <stringprep.h>
int stringprep_4i(uint32_t * ucs4, size_t * len, size_t maxucs4len, Stringprep_profile_flags flags, const Stringprep_profile * profile);
Prepare the input UCS-4 string according to the stringprep profile, and write back the result to the input string.
The input is not required to be zero terminated ( ucs4 [ len ] = 0). The output will not be zero terminated unless ucs4 [ len ] = 0. Instead, see stringprep_4zi() if your input is zero terminated or if you want the output to be.
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.
