/**
|
|
* idna_strerror:
|
|
* @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.
