lcaClear

Calling Sequence

lcaClear(pvs)

Description

Clear / release (disconnect) channels. This is particularly useful with EPICS 3.14 to clean up invalid PVs (e.g., due to typos). Nonexisting PVs are continuously searched for by a CA background task which may result in cluttered IOC consoles and resource consumption. All monitors on the target channel(s) are cancelled/released as a consequence of this call.

Parameters

pvs

Column vector (in matlab: m x 1 cell- matrix) of m strings. Alternatively, lcaClear may be called with no rhs argument thus clearing all channels (and monitors).

Examples

\\ clear a number of channels
  lcaClear( ['aUseless_PV'; 'misTyppedPV' ] )
\\ purge all channels (dont use parenthesis in matlab)
  lcaClear()
