NAME

6       idn2_to_ascii_4z - API function
7

SYNOPSIS

9       #include <idn2.h>
10
11       int  idn2_to_ascii_4z(const  uint32_t  *  input,  char  **  output, int
12       flags);
13

ARGUMENTS

15       const uint32_t * input
16                   zero terminated input Unicode (UCS-4) string.
17
18       char ** output
19                   pointer to newly allocated zero-terminated output string.
20
21       int flags   optional idn2_flags to modify behaviour.
22

DESCRIPTION

24       Convert UCS-4 domain name to ASCII string  using  the  IDNA2008  rules.
25       The  domain  name  may  contain several labels, separated by dots.  The
26       output buffer must be deallocated by the caller.
27
28       The default behavior of this function (when flags are zero) is to apply
29       the IDNA2008 rules without the TR46 amendments. As the TR46 non-transi‐
30       tional processing is nowadays ubiquitous, when  unsure,  it  is  recom‐
31       mended  to  call  this  function  with the IDN2_NONTRANSITIONAL and the
32       IDN2_NFC_INPUT flags for compatibility with other software.
33
34       Return value: Returns IDN2_OK on success, or error code.
