+/**
+ * stringprep_strerror:
+ * @rc: a #Stringprep_rc return code.
+ *
+ * Convert a return code integer to a text string.  This string can be
+ * used to output a diagnostic message to the user.
+ *
+ * STRINGPREP_OK: Successful operation.  This value is guaranteed to
+ *   always be zero, the remaining ones are only guaranteed to hold
+ *   non-zero values, for logical comparison purposes.
+ * STRINGPREP_CONTAINS_UNASSIGNED: String contain unassigned Unicode
+ *   code points, which is forbidden by the profile.
+ * STRINGPREP_CONTAINS_PROHIBITED: String contain code points
+ *   prohibited by the profile.
+ * STRINGPREP_BIDI_BOTH_L_AND_RAL: String contain code points with
+ *   conflicting bidirection category.
+ * STRINGPREP_BIDI_LEADTRAIL_NOT_RAL: Leading and trailing character
+ *   in string not of proper bidirectional category.
+ * STRINGPREP_BIDI_CONTAINS_PROHIBITED: Contains prohibited code
+ *   points detected by bidirectional code.
+ * STRINGPREP_TOO_SMALL_BUFFER: Buffer handed to function was too
+ *   small.  This usually indicate a problem in the calling
+ *   application.
+ * STRINGPREP_PROFILE_ERROR: The stringprep profile was inconsistent.
+ *   This usually indicate an internal error in the library.
+ * STRINGPREP_FLAG_ERROR: The supplied flag conflicted with profile.
+ *   This usually indicate a problem in the calling application.
+ * STRINGPREP_UNKNOWN_PROFILE: The supplied profile name was not
+ *   known to the library.
+ * STRINGPREP_ICONV_ERROR: Could not convert string in locale encoding.
+ * STRINGPREP_NFKC_FAILED: The Unicode NFKC operation failed.  This
+ *   usually indicate an internal error in the library.
+ * STRINGPREP_MALLOC_ERROR: The malloc() was out of memory.  This is
+ *   usually a fatal error.
+ *
+ * Return value: Returns a pointer to a statically allocated string
+ *   containing a description of the error with the return code @rc.
