Declaration
function FLock: WordBool;
Description
Locks the current table.
Return Value
True if the lock was successful and False if not. In Windows, SHARE.EXE should be loaded at the work station in order to achieve consistent file lock results.
Apollo will retry locks according to the time-out value set via SetLockTimeout before returning a lock failure.
Delphi Example
// Reindex example
with ApTbl do
begin
Open;
IndexOpen( 'c:\Apollo\sxlog1.ntx' );
IndexOpen( 'c:\Apollo\sxlog2.ntx' );
if FLock then
begin
SetGaugeHook( Gauge1.Handle );
// Global to set gauge proportion
GaugeFiles := 2;
Reindex;
SetGaugeHook( 0 );
Unlock( 0 );
end
else
ShowMessage( 'Lock failed. Try again later.' );
end;
