idn2_to_ascii_8z(3) libidn2 idn2_to_ascii_8z(3)
NAME
idn2_to_ascii_8z - API function
SYNOPSIS
#include <idn2.h>
int idn2_to_ascii_8z(const char * input, char ** output, int flags);
ARGUMENTS
const char * input
zero terminated input UTF-8 string.
char ** output
pointer to newly allocated output string.
int flags optional idn2_flags to modify behaviour.
DESCRIPTION
Convert UTF-8 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-transi-
tional processing is nowadays ubiquitous, when unsure, it is recom-
mended 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.

2.0.0
