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.
