IoGetDriverProxyEndpointWrapper function (wdm.h)

The IoGetDriverProxyEndpointWrapper function gets the pointer to the wrapper for an endpoint function using a function ID in Driver Hot-Swap V1 implementations.

Syntax

PDRIVER_PROXY_WRAPPED_ENDPOINT_FUNCTION IoGetDriverProxyEndpointWrapper(
  PDRIVER_PROXY_EXTENSION           DriverProxyExtension,
  DRIVER_PROXY_ENDPOINT_FUNCTION_ID FunctionId
);

Parameters

DriverProxyExtension

[in] A pointer to the DriverProxy extension that contains the registered endpoints.

FunctionId

[in] The function ID of the endpoint function to search for. This is a deprecated mechanism for identifying endpoint functions.

Return value

IoGetDriverProxyEndpointWrapper returns a pointer to the endpoint wrapper function, or NULL if the specified function ID could not be found.

Remarks

This function is only available in Driver Hot-Swap V1 and is not supported in Driver Hot-Swap V2. New drivers should use Driver Hot-Swap V2 with IoGetDriverProxyWrapperFromEndpoint instead.

The function ID approach was used in the original Driver Hot-Swap implementation but is not part of the current Driver Hot-Swap V2 system.
