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);
| required_major | the required major version. | |
| required_minor | the required minor version. | |
| required_micro | the required micro version. | 
 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.
