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.
