lineGetAddressStatus

The lineGetAddressStatus function allows an application to query the specified address for its current status.

LONG lineGetAddressStatus(
  HLINE hLine,                         
  DWORD dwAddressID,                   
  LPLINEADDRESSSTATUS lpAddressStatus  
);
 

Parameters

dwAddressID

An address on the given open line device. This is the address to be queried.

lpAddressStatus
