- Unused
This parameter is not used and should be set to NULL.
- iDevNum
[in] Index value that specifies the display device of interest.
The operating system identifies each display device with an index value. The index values are consecutive integers, starting at 0. If a system has three display devices, for example, they are specified by the index values 0, 1, and 2.
- lpDisplayDevice
[out] Pointer to a DISPLAY_DEVICE structure that receives information about the display device specified by iDevNum.
Before calling EnumDisplayDevices, you must initialize the cb member of DISPLAY_DEVICE to the size, in bytes, of DISPLAY_DEVICE.
- dwFlags
This parameter is currently not used and should be set to zero. |
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. The function fails if iDevNum is greater than the largest device index. |
