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_NFKC_FAILED: The Unicode NFKC operation failed. This
69 : : * usually indicate an internal error in the library.
70 : : * STRINGPREP_MALLOC_ERROR: The malloc() was out of memory. This is
71 : : * usually a fatal error.
72 : : *
73 : : * Return value: Returns a pointer to a statically allocated string
74 : : * containing a description of the error with the return code @rc.
