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 suitable 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.
