This function is superseded by the DirectDrawEnumerateEx function.

The DirectDrawEnumerate function enumerates the primary DirectDraw display device and a nondisplay device (such as a 3-D accelerator that has no 2-D capabilities), if one is installed. The NULL entry always identifies the primary display device shared with the GDI.

Syntax

HRESULT DirectDrawEnumerateW(
  [in] LPDDENUMCALLBACKW lpCallback,
  [in] LPVOID            lpContext
);

Parameters

[in] lpCallback

Address of a DDEnumCallback function to be called with a description of each enumerated DirectDraw-enabled hardware abstraction layer (HAL).

[in] lpContext

Address of an application-defined context to be passed to the enumeration callback function each time that it is called.

Return value

If the function succeeds, the return value is DD_OK.

If it fails, the function returns DDERR_INVALIDPARAMS.

Remarks

You must use LoadLibrary to explicitly link to Ddraw.dll and then use GetProcAddress to access the DirectDrawEnumerate function.
