 40  : * stringprep_strerror:
 41  : * @rc: a #Stringprep_rc return code.
 42  : *
 43  : * Convert a return code integer to a text string. This string can be
 44  : * used to output a diagnostic message to the user.
 45  : *
 46  : * STRINGPREP_OK: Successful operation. This value is guaranteed to
 47  : * always be zero, the remaining ones are only guaranteed to hold
 48  : * non-zero values, for logical comparison purposes.
 49  : * STRINGPREP_CONTAINS_UNASSIGNED: String contain unassigned Unicode
 50  : * code points, which is forbidden by the profile.
 51  : * STRINGPREP_CONTAINS_PROHIBITED: String contain code points
 52  : * prohibited by the profile.
 53  : * STRINGPREP_BIDI_BOTH_L_AND_RAL: String contain code points with
 54  : * conflicting bidirection category.
 55  : * STRINGPREP_BIDI_LEADTRAIL_NOT_RAL: Leading and trailing character
 56  : * in string not of proper bidirectional category.
 57  : * STRINGPREP_BIDI_CONTAINS_PROHIBITED: Contains prohibited code
 58  : * points detected by bidirectional code.
 59  : * STRINGPREP_TOO_SMALL_BUFFER: Buffer handed to function was too
 60  : * small. This usually indicate a problem in the calling
 61  : * application.
 62  : * STRINGPREP_PROFILE_ERROR: The stringprep profile was inconsistent.
 63  : * This usually indicate an internal error in the library.
 64  : * STRINGPREP_FLAG_ERROR: The supplied flag conflicted with profile.
 65  : * This usually indicate a problem in the calling application.
 66  : * STRINGPREP_UNKNOWN_PROFILE: The supplied profile name was not
 67  : * known to the library.
 68  : * STRINGPREP_ICONV_ERROR: Character encoding conversion error.
 69  : * STRINGPREP_NFKC_FAILED: The Unicode NFKC operation failed. This
 70  : * usually indicate an internal error in the library.
 71  : * STRINGPREP_MALLOC_ERROR: The malloc() was out of memory. This is
 72  : * usually a fatal error.
 73  : *
 74  : * Return value: Returns a pointer to a statically allocated string
 75  : * containing a description of the error with the return code @rc.
