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.
extern const guint gtk_major_version;
The major version number of the GTK+ library. (e.g. in GTK+ version 1.2.5 this is 1.)
This variable is in the library, so represents the GTK+ library you have linked against. Contrast with the GTK_MAJOR_VERSION macro, which represents the major version of the GTK+ headers you have included.
extern const guint gtk_minor_version;
The minor version number of the GTK+ library. (e.g. in GTK+ version 1.2.5 this is 2.)
This variable is in the library, so represents the GTK+ library you have linked against. Contrast with the GTK_MINOR_VERSION macro, which represents the minor version of the GTK+ headers you have included.
extern const guint gtk_micro_version;
The micro version number of the GTK+ library. (e.g. in GTK+ version 1.2.5 this is 5.)
This variable is in the library, so represents the GTK+ library you have linked against. Contrast with the GTK_MICRO_VERSION macro, which represents the micro version of the GTK+ headers you have included.
extern const guint gtk_binary_age;
This is the binary age passed to libtool. If libtool means nothing to you, don't worry about it. ;-)
extern const guint gtk_interface_age;
This is the interface age passed to libtool. If libtool means nothing to you, don't worry about it. ;-)
gchar* 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_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 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+.
required_major : | the required major version. |
required_minor : | the required major version. |
required_micro : | the required major version. |
Returns : | NULL if the GTK+ library is compatible with the given version, or a string describing the version mismatch. The returned string is owned by GTK+ and should not be modified or freed. |
#define GTK_MAJOR_VERSION (2)
Like gtk_major_version, but from the headers used at application compile time, rather than from the library linked against at application run time.
#define GTK_MINOR_VERSION (6)
Like gtk_minor_version, but from the headers used at application compile time, rather than from the library linked against at application run time.
#define GTK_MICRO_VERSION (2)
Like gtk_micro_version, but from the headers used at application compile time, rather than from the library linked against at application run time.
#define GTK_BINARY_AGE (602)
Like gtk_binary_age, but from the headers used at application compile time, rather than from the library linked against at application run time.
#define GTK_INTERFACE_AGE (2)
Like gtk_interface_age, but from the headers used at application compile time, rather than from the library linked against at application run time.
#define GTK_CHECK_VERSION(major,minor,micro)
Returns TRUE if the version of the GTK+ header files is the same as or newer than the passed-in version.
major : | major version (e.g. 1 for version 1.2.5) |
minor : | minor version (e.g. 2 for version 1.2.5) |
micro : | micro version (e.g. 5 for version 1.2.5) |
