Called by the operating system to query the Miracast user-mode driver interface, MIRACAST_DRIVER_INTERFACE.

Syntax

QUERY_MIRACAST_DRIVER_INTERFACE QueryMiracastDriverInterface;

NTSTATUS QueryMiracastDriverInterface(
  [in]  UINT MiracastDriverInterfaceVersion,
  [in]  UINT MiracastDriverInterfaceSize,
  [out] VOID *pMiracastDriverInterface
)
{...}

Parameters

[in] MiracastDriverInterfaceVersion

The version of the Miracast display interface, supplied by the operating system.

This version is defined in Netdispumdddi.h as a MIRACAST_DRIVER_INTERFACE_VERSION_XXX value. For Windows 8.1, the value is MIRACAST_DRIVER_INTERFACE_VERSION_1.

[in] MiracastDriverInterfaceSize

The size, supplied by the operating system, of the buffer pointed to by pMiracastDriverInterface.

[out] pMiracastDriverInterface

A pointer to a buffer, supplied by the operating system, that holds the returned Miracast display driver interface, which is a structure of type MIRACAST_DRIVER_INTERFACE.

Return value

On success, this function returns STATUS_SUCCESS. Otherwise, the function returns an error code defined in the Ntstatus.h header.

Remarks

When the Miracast user-mode driver is loaded, the operating system calls the GetProcAddress function with "QueryMiracastDriverInterface" entered as the function name in the lpProcName parameter.

Note If the Miracast user-mode driver doesn't supply a function with this name, the operating system fails the Miracast display device.
