NAME

6       idn2_to_ascii_8z - API function
7

SYNOPSIS

9       #include <idn2.h>
10
11       int idn2_to_ascii_8z(const char * input, char ** output, int flags);
12

ARGUMENTS

14       const char * input
15                   zero terminated input UTF-8 string.
16
17       char ** output
18                   pointer to newly allocated output string.
19
20       int flags   optional idn2_flags to modify behaviour.
21

DESCRIPTION

23       Convert  UTF-8  domain  name  to ASCII string using the IDNA2008 rules.
24       The domain name may contain several labels,  separated  by  dots.   The
25       output buffer must be deallocated by the caller.
26
27       The default behavior of this function (when flags are zero) is to apply
28       the IDNA2008 rules without the TR46 amendments. As the TR46 non-transi‐
29       tional  processing  is  nowadays  ubiquitous, when unsure, it is recom‐
30       mended to call this function  with  the  IDN2_NONTRANSITIONAL  and  the
31       IDN2_NFC_INPUT flags for compatibility with other software.
32
33       Return value: Returns IDN2_OK on success, or error code.
