NAME
DeviceProc -- Return the process MsgPort of specific I/O handler
SYNOPSIS
process = DeviceProc( name )
D0 D1
struct MsgPort *DeviceProc (STRPTR)Links: MsgPort
FUNCTION
DeviceProc() returns the process identifier of the process which handles the device associated with the specified name. If no process handler can be found then the result is zero. If the name refers to an assign then a directory lock is returned in IoErr. This lock should not be UnLock()ed or Examine()ed (if you wish to do so, DupLock it first).
BUGS In V36, if you try to DeviceProc() something relative to an assign made with AssignPath, it will fail. This is because there's no way to know when to unlock the lock. If you're writing code for V36 or later, it is highly advised you use GetDeviceProc instead, or make your code conditional on V36 to use GetDeviceProc()/ FreeDeviceProc.
