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.
