/**
 * tld_strerror:
 * @rc: tld return code
 *
 * Convert a return code integer to a text string.  This string can be
 * used to output a diagnostic message to the user.
 *
 * TLD_SUCCESS: 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.
 * TLD_INVALID: Invalid character found.
 * TLD_NODATA: No input data was provided.
 * TLD_MALLOC_ERROR: Error during memory allocation.
 * TLD_ICONV_ERROR: Character encoding conversion error.
 * TLD_NO_TLD: No top-level domain found in domain string.
 *
 * Return value: Returns a pointer to a statically allocated string
 * containing a description of the error with the return code @rc.
