Description
Acquiring a read or write lock automatically synchronizes the internals
of the table tool with the actual contents of the table files.
In this way different processes accessing the same table always
use the same table data.
However, a table can be used without read locking. In that case
the table tool internals are not synchronized automatically.
The resync function offers a way to do explicit synchronization.
It is only useful if the table is opened with locking mode
autonoread or
usernoread.
