NAME¶
idn2_register_ul - API function
SYNOPSIS¶
#include <idn2.h>
int idn2_register_ul(const char * ulabel, const char *
alabel, char ** insertname, int
flags);
ARGUMENTS¶
- const char * ulabel
- input zero-terminated locale encoded string, or NULL.
- const char * alabel
- input zero-terminated ACE encoded string (xn--), or NULL.
- char ** insertname
- newly allocated output variable with name to register in DNS.
- int flags
- optional idn2_flags to modify behaviour.
DESCRIPTION¶
Perform IDNA2008 register string conversion on domain label
ulabel and
alabel, as described in section 4 of RFC 5891. Note that the input
ulabel is assumed to be encoded in the locale's default coding system,
and will be transcoded to UTF-8 and NFC normalized by this function.
It is recommended to supply both
ulabel and
alabel for better
error checking, but supplying just one of them will work. Passing in only
alabel is better than only
ulabel. See RFC 5891 section 4 for
more information.
RETURNS¶
On successful conversion
IDN2_OK is returned, when the given
ulabel and
alabel does not match each other
IDN2_UALABEL_MISMATCH is returned, when either of the input labels are
too long
IDN2_TOO_BIG_LABEL is returned, when
alabel does does
not appear to be a proper A-label
IDN2_INVALID_ALABEL is returned, or
another error code is returned.
