| 53 | Return the current video mode information.\r | |
| 54 | \r | |
| 55 | Arguments:\r | |
| 56 | This - Protocol instance pointer.\r | |
| 57 | ChildHandle - A child handle produced by the Graphics Output EFI\r | |
| 58 | driver that represents a video output device. \r | |
| 59 | Attributes - The attributes associated with ChildHandle video output device.\r | |
| 60 | EdidSize - A pointer to the size, in bytes, of the Edid buffer.\r | |
| 61 | Edid - A pointer to callee allocated buffer that contains the EDID that\r | |
| 62 | should be used for ChildHandle. A value of NULL \r | |
| 63 | represents no EDID override for ChildHandle.\r | |
| 64 | \r | |
| 65 | Returns:\r | |
| 66 | EFI_SUCCESS - Valid overrides returned for ChildHandle.\r | |
| 67 | EFI_UNSUPPORTED - ChildHandle has no overrides.\r | |
