idn2_to_ascii_4z(3)                 libidn2                idn2_to_ascii_4z(3)

NAME
       idn2_to_ascii_4z - API function

SYNOPSIS
       #include <idn2.h>

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

ARGUMENTS
       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.

DESCRIPTION
       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.

SINCE
       2.0.0
