*LOCKIO (GETMODE)


PLBCMP Only

*LOCKIO={value}

 

This control is now obsolete.

 

The *LOCKIO control reports the state of the forced I/O locks.

 

The need for this type of lock request was to work around a problem in Microsoft's Network Redirector for Windows 95 that was causing data corruption when multiple Windows 95 workstations were accessing the same files. Please note that Microsoft's Network Redirector was modified to correct this data corruption problem such that the need for the Sunbelt I/O lock requirements should no longer be needed. The ability to turn the I/O lock requests are only being made available in cases where Microsoft's Network Redirector correction is not being used. The Microsoft solution for the data corruption was documented as problem Q148367 and was made available 24 Sept 1997.

 

{value} is a previously defined Numeric Variable that returns the current state of the forced IO locks.

 

The {value} returned is one of the following:

0
