Class TFindLogicalChannel

TFindLogicalChannel

Support

Supported from 5.0

Description

Searches for logical channels by pattern matching against the names of (Kernel side) logical channel objects.

The match pattern can be set into this object at construction; it can also be changed at any time after construction by using TFindHandleBase::Find().

After construction, call TFindLogicalChannel::Next() repeatedly to find successive logical channels whose names match the current pattern. A successful call to TFindLogicalChannel::Next() means that a matching logical channel has been found.

The name of a logical channel is usually set when it is created through the User side call to RBusLogicalChannel::DoCreate().
