idn2_check_version(3) libidn2 idn2_check_version(3)NAME
idn2_check_version - API function
SYNOPSIS
#include <idn2.h>
const char * idn2_check_version(const char * req_version);
ARGUMENTS
const char * req_version
version string to compare with, or NULL.
DESCRIPTION
Check IDN2 library version. This function can also be used to read out the version of the library code used. See IDN2_VERSION for a suit-
able req_version string, it corresponds to the idn2.h header file version. Normally these two version numbers match, but if you are using
an application built against an older libidn2 with a newer libidn2 shared library they will be different.
RETURN VALUE
Check that the version of the library is at minimum the one given as a string in req_version and return the actual version string of the
library; return NULL if the condition is not met. If NULL is passed to this function no check is done and only the version string is
returned.

ARGUMENTS
const char * src
input zero-terminated locale encoded string.

newly allocated output variable with name to lookup in DNS.
int flags optional idn2_flags to modify behaviour.
DESCRIPTION
Perform IDNA2008 lookup string conversion on domain name src, as described in section 5 of RFC 5891. Note that the input 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.
Pass IDN2_ALABEL_ROUNDTRIP in flags to convert any input A-labels to U-labels and perform additional testing.
RETURNS

domain or any label would have been too long IDN2_TOO_BIG_DOMAIN or IDN2_TOO_BIG_LABEL is returned, or another error code is returned.
