const char* gtk_check_version ( guint required_major, guint required_minor, guint required_micro )
Checks that the GTK library in use is compatible with the given version.
Generally you would pass in the constants
GTK_MICRO_VERSION as the three arguments
to this function; that produces a check that the library in
use is compatible with the version of GTK the application or
module was compiled against.
Compatibility is defined by two things: first the version
of the running library is newer than the version
the running library must be binary compatible with the
(same major version.)
This function is primarily for GTK modules; the module can call this function to check that it wasn’t loaded into an incompatible version of GTK. However, such a check isn’t completely reliable, since the module may be linked against an old version of GTK and calling the old version of gtk_check_version(), but still get loaded into an application using a newer version of GTK.
