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_UNICODECONV), 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 validate 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));
}
...
