Checks that the GTK+ library in use is compatible with the given version. Generally you would pass in the constants GTK_MAJOR_VERSION, GTK_MINOR_VERSION, 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 required_major.required_minor.required_micro. Second the running library must be binary compatible with the version required_major.required_minor.required_micro (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+.
Returns the binary age as passed to libtool when building the GTK+ library the process is running against. If libtool means nothing to you, don't worry about it.
Returns the interface age as passed to libtool when building the GTK+ library the process is running against. If libtool means nothing to you, don't worry about it.
Returns the major version number of the GTK+ library. (e.g. in GTK+ version 3.1.5 this is 3.) This function is in the library, so it represents the GTK+ library your code is running against. Contrast with the GTK_MAJOR_VERSION macro, which represents the major version of the GTK+ headers you have included when compiling your code.
Returns the micro version number of the GTK+ library. (e.g. in GTK+ version 3.1.5 this is 5.) This function is in the library, so it represents the GTK+ library your code is are running against. Contrast with the GTK_MICRO_VERSION macro, which represents the micro version of the GTK+ headers you have included when compiling your code.
Returns the minor version number of the GTK+ library. (e.g. in GTK+ version 3.1.5 this is 1.) This function is in the library, so it represents the GTK+ library your code is are running against. Contrast with the GTK_MINOR_VERSION macro, which represents the minor version of the GTK+ headers you have included when compiling your code.
GTK+ provides version information, primarily useful in configure checks for builds that have a configure script. Applications will not typically use the features described here.
