Function DbRUnlock() Foundation
Release record locks in a work area.
DbRUnlock( [<xRecordID>] ) --> NIL
The return value of DbRUnlock() is always NIL.
The database function DbRUnlock() releases existing record locks in a work area. If a record ID <xRecordID> is specified, the record lock is released only for this record. The function DbRUnlock() allows selective releasing of individual locks when multiple data records are locked in a work area. This is not possible with the function DbUnlock(). If no record ID is specified, DbRUnlock() behaves like DbUnlock(), meaning all existing record locks are released. If the function is called without the alias operator, it releases the locks in the current work area. This function is only meaningful when files are open in the SHARED mode.
