The acxrequest header is used by the ACX audio class extensions.
For additional information on working with ACX, see the following topics.
acxrequest.h contains the following programming interfaces:
Functions
| ACX_REQUEST_PARAMETERS_INIT The ACX_REQUEST_PARAMETERS_INIT function initializes ACX_REQUEST_PARAMETERS struct. |
| ACX_REQUEST_PARAMETERS_INIT_METHOD The ACX_REQUEST_PARAMETERS_INIT_METHOD initializes an ACX_REQUEST_PARAMETERS struct with ACX method parameters. |
| ACX_REQUEST_PARAMETERS_INIT_PROPERTY The ACX_REQUEST_PARAMETERS_INIT_PROPERTY initializes an ACX_REQUEST_PARAMETERS struct with ACX property parameters. |
| AcxRequestGetParameters The AcxRequestGetParameters function gets ACX request parameters from a WDFREQUEST. |
Callback functions
| EVT_ACX_OBJECT_PREPROCESS_REQUEST The EVT_ACX_OBJECT_PREPROCESS_REQUEST callback is used by the driver to preprocess I/O WDFREQUESTs. |
| EVT_ACX_OBJECT_PROCESS_EVENT_REQUEST The EVT_ACX_OBJECT_PROCESS_EVENT_REQUEST callback is used by the driver to handle event notifications. |
| EVT_ACX_OBJECT_PROCESS_REQUEST The EVT_ACX_OBJECT_PROCESS_REQUEST callback is used by the driver to handle a WDFREQUEST. |
Structures
| ACX_EVENT_ITEM The ACX_EVENT_ITEM structure describes an event item that is the target of an ACX request. |
| ACX_METHOD_ITEM The ACX_METHOD_ITEM structure describes a method item that is the target of an ACX request. |
| ACX_PROPERTY_ITEM The ACX_PROPERTY_ITEM structure describes a property item that is the target of an ACX request. |
| ACX_REQUEST_PARAMETERS The ACX_REQUEST_PARAMETERS structure receives parameters that are associated with an I/O ACX request. |
