+/**
+ * idna_strerror - return string describing idna error code
+ * @rc: an #Idna_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.
+ *
+ * IDNA_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.
+ * IDNA_STRINGPREP_ERROR:  Error during string preparation.
+ * IDNA_PUNYCODE_ERROR: Error during punycode operation.
+ * IDNA_CONTAINS_NON_LDH: For IDNA_USE_STD3_ASCII_RULES, indicate that
+ *   the string contains non-LDH ASCII characters.
+ * IDNA_CONTAINS_MINUS: For IDNA_USE_STD3_ASCII_RULES, indicate that
+ *   the string contains a leading or trailing hyphen-minus (U+002D).
+ * IDNA_INVALID_LENGTH: The final output string is not within the
+ *   (inclusive) range 1 to 63 characters.
+ * IDNA_NO_ACE_PREFIX: The string does not contain the ACE prefix
+ *   (for ToUnicode).
+ * IDNA_ROUNDTRIP_VERIFY_ERROR: The ToASCII operation on output
+ *   string does not equal the input.
+ * IDNA_CONTAINS_ACE_PREFIX: The input contains the ACE prefix (for
+ *   ToASCII).
+ * IDNA_ICONV_ERROR: Could not convert string in locale encoding.
+ * IDNA_MALLOC_ERROR: Could not allocate buffer (this is typically a
+ *   fatal error).
+ * IDNA_DLOPEN_ERROR: Could not dlopen the libcidn DSO (only used
+ *   internally in libc).
+ *
+ * Return value: Returns a pointer to a statically allocated string
+ * containing a description of the error with the return code @rc.
