idn_checkname(3)idn_checkname(3)NAMEidn_checkname - validate an internationalized domain name
SYNOPSIS
#include <idn/api.h>
idn_result_t
idn_checkname(idn_action_t actions, const char *from);
DESCRIPTION
The function idn_checkname() internally creates a copy of name, encodes
it with idn_encodename() and returns its error code.
In addition with action macros for idn_encodename() (e.g. IDN_UNICODE‐
CONV), the following macros are available for idn_checkname().
IDN_CHECK_REGIST
Encode a domain name with IDNA2008 registration protocol to
validate a domain name. Currently, its value is the same as
IDN_ENCODE_REGIST.
IDN_CHECK_LOOKUP
Encode a domain name with IDNA2008 lookup protocol to vali‐
date a domain name. Currently, its value is the same as
IDN_ENCODE_LOOKUP.
EXAMPLES
The program below shows an example of idn_checkname().
idn_result_t r;
...
r = idn_checkname(IDN_CHECK_REGIST, name);
if (r == idn_success)
fprintf(stderr, "'%s' is valid\n", name);
else {
fprintf(stderr, "'%s' is not valid: %s\n",
name, idn_result_tostring(r));
}
