User-defined ECPs

A filter driver can define its own extra create parameters (ECPs). To define your own ECP:

  • Define a GUID that identifies your ECP.

  • Define a context structure that describes your ECP.

See System-defined ECPs for examples of system-defined GUIDs and associated context structures.

For information about how to define GUIDs and using them in driver code, see Using GUIDs in Drivers.
