This method returns the sharpness setting of this RenderingControl instance.

Syntax 

virtual DWORD GetSharpness(
  unsigned short* 
pSharpness
) = 0;

Parameters

pSharpness

[in, out] Sharpness setting of this RenderingControl instance. Corresponds to the Sharpness state variable.

Return Value

Custom implementations can return appropriate error codes. Should return SUCCESS_AV if the method succeeds. Otherwise, should return an error code defined in WinError.h or UPnP.h, or one of the UPnP AV-specific return values specified in UPnPAVError, especially the following errors documented for this action in the RenderingControl DCP documentation:

  • ERROR_AV_UPNP_ACTION_FAILED

  • ERROR_AV_UPNP_RC_INVALID_INSTANCE_ID

Remarks

This method corresponds to the RenderingControl service's GetSharpness action.

The RenderingControl service does not require that this method be implemented. The IRenderingControlImplclass therefore overrides this method to return ERROR_AV_UPNP_INVALID_ACTION.

For more information about the actions in the RenderingControl service, see UPnP AV DCP Documentation.

Requirements

Header av_upnp.h
Library Av_upnp.lib
Windows Embedded CE Windows CE 5.0 and later
Windows Mobile Windows Mobile Version 5.0 and later
