evntprov.h contains the following programming interfaces:
Functions
| EventActivityIdControl Creates, queries, and sets activity identifiers for use in ETW events. |
| EventDataDescCreate Sets the values of an EVENT_DATA_DESCRIPTOR. |
| EventDescCreate Sets the values of an event descriptor. |
| EventDescGetChannel Retrieves the channel from the event descriptor. |
| EventDescGetId Retrieves the event identifier from the event descriptor. |
| EventDescGetKeyword Retrieves the keyword from the event descriptor. |
| EventDescGetLevel Retrieves the severity level from the event descriptor. |
| EventDescGetOpcode Retrieves the operation code from the event descriptor. |
| EventDescGetTask Retrieves the task from the event descriptor. |
| EventDescGetVersion Retrieves the version from the event descriptor. |
| EventDescOrKeyword Adds another keyword to the event descriptor. |
| EventDescSetChannel Sets the Channel member of the event descriptor. |
| EventDescSetId Sets the Id member of the event descriptor. |
| EventDescSetKeyword Sets the Keyword member of the event descriptor. |
| EventDescSetLevel Sets the Level member of the event descriptor. |
| EventDescSetOpcode Sets the Opcode member of the event descriptor. |
| EventDescSetTask Sets the Task member of the event descriptor. |
| EventDescSetVersion Sets the Version member of the event descriptor. |
| EventDescZero Initializes an event descriptor to zero. |
| EventEnabled Determines whether an event provider should generate a particular event based on the event's EVENT_DESCRIPTOR. |
| EventProviderEnabled Determines whether an event provider should generate a particular event based on the event's Level and Keyword. |
| EventRegister Registers an ETW event provider, creating a handle that can be used to write ETW events. |
| EventSetInformation Configures an ETW event provider. |
| EventUnregister Unregisters an ETW event provider. |
| EventWrite Writes an ETW event that uses the current thread's activity ID. |
| EventWriteEx Writes an ETW event with an activity ID, an optional related activity ID, session filters, and special options. |
| EventWriteString Writes an ETW event that contains a string as its data. This function should not be used. |
| EventWriteTransfer Writes an ETW event with an activity ID and an optional related activity ID. |
Callback functions
| PENABLECALLBACK ETW event providers optionally define an EnableCallback function to receive configuration change notifications. The PENABLECALLBACK type defines a pointer to this callback function. EnableCallback is a placeholder for the application-defined function name. |
Structures
| EVENT_DATA_DESCRIPTOR The EVENT_DATA_DESCRIPTOR structure defines a block of data that will be used in an ETW event. |
| EVENT_DESCRIPTOR The EVENT_DESCRIPTOR structure contains information (metadata) about an ETW event. |
| EVENT_FILTER_DESCRIPTOR Defines the filter data that a session passes to the provider's enable callback function. |
| EVENT_FILTER_EVENT_ID Defines event IDs used in an EVENT_FILTER_DESCRIPTOR structure for an event ID or stack walk filter. |
| EVENT_FILTER_EVENT_NAME Defines event IDs used in an EVENT_FILTER_DESCRIPTOR structure for an event name or stalk walk name filter. |
| EVENT_FILTER_HEADER Defines the header data that must precede the filter data that is defined in the instrumentation manifest. |
| EVENT_FILTER_LEVEL_KW Defines event IDs used in an EVENT_FILTER_DESCRIPTOR structure for a stack walk level-keyword filter. |
Enumerations
| EVENT_INFO_CLASS The EVENT_INFO_CLASS enumeration type is used with the EventSetInformation function to specify the configuration operation to be performed on an ETW event provider registration. |
