tumbler_check_version ()
const gchar *
tumbler_check_version (guint required_major
,
guint required_minor
,
guint required_micro
);
Checks that the tumbler
library
in use is compatible with the given version. Generally you would pass in
the constants TUMBLER_MAJOR_VERSION, TUMBLER_MINOR_VERSION and
TUMBLER_MICRO_VERSION as the three arguments to this function; that
produces a check that the library in use is compatible with the version
of tumbler
the application was
compiled against.
Example 1. Checking the runtime version of the tumbler library

const gchar *mismatch;
mismatch = tumbler_check_version (TUMBLER_VERSION_MAJOR,
TUMBLER_VERSION_MINOR,
TUMBLER_VERSION_MICRO);
if (G_UNLIKELY (mismatch != NULL))
g_error ("Version mismatch: %s", mismatch); |
Returns
NULL
if the library is compatible with the given version,
or a string describing the version mismatch. The returned
string is owned by the library and must not be freed or
modified by the caller.
