Auxiliary display device driver interface

In a computing environment, a method comprising:

• providing an interface set comprising logical auxiliary display operations with at least one interface,
• the at least one interface of the interface set being implemented by an auxiliary display device driver to couple the auxiliary display device driver to a separate auxiliary display platform,
• the auxiliary display device driver implementing the at least one interface of the interface set to send commands corresponding to logical auxiliary display operations to at least one auxiliary display device,
• the auxiliary display device driver implementing the at least one interface of the interface set to send device event data received from the at least one auxiliary display device to the auxiliary display platform;
• and
• calling into the auxiliary display device driver via the at least one interface of the interface set, including making calls corresponding to commands received from the auxiliary display platform to be performed by the at least one auxiliary display device.

In a computing environment having a main computer system and an auxiliary display device, a system comprising:

• an auxiliary display platform that provides data directed towards the auxiliary display device from one or more application programs;
• an auxiliary display device driver that receives the data from the auxiliary display platform and provides corresponding information to the auxiliary display device via a transport;
• an interface set comprising logical auxiliary display operations implemented by the auxiliary display device driver, wherein the interface set comprises code that is external to the auxiliary display device driver;
• and
• a class extension object that communicates with the auxiliary display device driver via the interface set, the class extension object configured to process commands received as data from the auxiliary display platform and to call back to the auxiliary display device driver via the interface with corresponding data, for providing as the corresponding information to the auxiliary display device via the transport, wherein the class extension object is also configured to send device event data received by the auxiliary display device driver from the auxiliary display device to the auxiliary display platform,
• wherein the interface set includes an interface that is used to create device event data for communicating events received from the auxiliary display device from the auxiliary display device driver to the auxiliary display platform.

A computer storage medium having computer-executable instructions stored thereon, the computer-executable instructions when implemented cause a computing device to perform steps, comprising:

• receiving by a defined interface set comprising logical auxiliary display operations with a call from an auxiliary display device driver, the call including a command related to performing an operation related to an auxiliary display, wherein the defined interface set comprises code that is external to the auxiliary display device driver;
• translating by the defined interface set the call and command into data in a data format understood by the auxiliary display device driver;
• and
• calling back the auxiliary display device driver with the data,
• wherein the call is received from the auxiliary display device driver via the defined interface set implemented by the auxiliary display device driver, and wherein calling back the auxiliary display device driver comprises returning the data via a call back registered via the defined interface set, and
• wherein the defined interface set is used to create device event data for communicating events received from the auxiliary display from the auxiliary display device driver to a separate auxiliary display platform.
