IMDSPDevice::SendOpaqueCommand method (mswmdm.h)

  • Article

The SendOpaqueCommand method sends a command through Windows Media Device Manager. Without acting on it, Windows Media Device Manager passes the command through to a device.

Syntax

HRESULT SendOpaqueCommand(
  [in, out] OPAQUECOMMAND *pCommand
);

Parameters

[in, out] pCommand

Pointer to an OPAQUECOMMAND structure containing the information required to execute the command.

Return value

The method returns an HRESULT. All the interface methods in Windows Media Device Manager can return any of the following classes of error codes:

  • Standard COM error codes
  • Windows error codes converted to HRESULT values
  • Windows Media Device Manager error codes
For an extensive list of possible error codes, see Error Codes.

Remarks

This method is used with device commands that do not affect Windows Media Device Manager, and are passed through unchanged. A more efficient way to call commands on a device is to call IMDSPDevice3::DeviceIoControl.

This method is optional. For more information, see Mandatory and Optional Interfaces.
