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.
