Tracker provides version information, primarily useful in configure checks for builds that have a configure script. Applications will not typically use the features described here.
const gchar * tracker_check_version (guint required_major
,guint required_minor
,guint required_micro
);
Checks that the Tracker library in use is compatible with the given version. Generally you would pass in the constants TRACKER_MAJOR_VERSION, TRACKER_MINOR_VERSION, TRACKER_MICRO_VERSION as the three arguments to this function; that produces a check that the library in use is compatible with the version of Tracker 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.)
required_major |
the required major version. |
|
required_minor |
the required minor version. |
|
required_micro |
the required micro version. |
NULL
if the Tracker library is compatible with the
given version, or a string describing the version mismatch.
The returned string is owned by Tracker and must not be modified
or freed.

#define TRACKER_CHECK_VERSION(major,minor,micro)
This macro essentially does the same thing as
tracker_check_version()
but as a pre-processor operation rather
than a run-time operation. It will evaluate true or false based the
version passed in and the version available.
Example 2. Simple version check example
if (!TRACKER_CHECK_VERSION (0, 10, 7)) { g_error ("Tracker version 0.10.7 or above is needed"); }
major |
the required major version. |
|
minor |
the required minor version. |
|
micro |
the required micro version. |
