const char* idna_strerror

idna_strerror - return string describing idna error code

Parameters:

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 .
