Releases a logical lock on a variable name.
||Name of the variable to be unlocked.
Each time a lock is obtained on a varname
a lock count is incremented. Unlock
decrements this count. Only when the lock count falls to zero will the logical lock be released. For this reason, you should balance each call to Lock
with a corresponding call to Unlock
The following example uses the Lock
function to obtain a logical lock on a global variable name (glvn) with a timeout of 10 seconds, and then uses the Unlock
function to release the logical lock.
If Lock(^PatientData(PatientID),10) = True Then
Println "Got the Lock"
Unlock(^PatientData(PatientID)) 'Release the logical lock
Println "Couldn't get the lock"
