### MODULE SUMMARY

This module implements the OMG CosNotifyChannelAdmin::EventChannelFactory interface.

### DESCRIPTION

### EXPORTS

create_channel(ChannelFactory, InitialQoS, InitialAdmin) -> Return

Types:

ChannelFactory = #objref

This operation creates a new event channel. Along with the channel reference an id is returned which can be used when invoking other operations exported by this module. The Quality of Service argument supplied will be inherited by objects created by the channel. For more information about QoS settings see the User's Guide.

If no QoS- and/or Admin-properties are supplied (i.e. empty list), the default settings will be used. For more information, see the User's Guide.
