idn2_to_ascii_4z - Man Page

API function


#include <idn2.h>

int idn2_to_ascii_4z(const uint32_t * input, char ** output, int flags);


const uint32_t * input

zero terminated input Unicode (UCS-4) string.

char ** output

pointer to newly allocated zero-terminated output string.

int flags

optional idn2_flags to modify behaviour.


Convert UCS-4 domain name to ASCII string using the IDNA2008 rules.  The domain name may contain several labels, separated by dots. The output buffer must be deallocated by the caller.

The default behavior of this function (when flags are zero) is to apply the IDNA2008 rules without the TR46 amendments. As the TR46 non-transitional processing is nowadays ubiquitous, when unsure, it is recommended to call this function with the IDN2_NONTRANSITIONAL and the IDN2_NFC_INPUT flags for compatibility with other software.

Return value: Returns IDN2_OK on success, or error code.
