| 30 | @param SizeOfEdid \r | |
| 31 | The size, in bytes, of the Edid buffer. 0 if no EDID information\r | |
| 32 | is available from the video output device. Otherwise, it must be a\r | |

| 36 | A pointer to a read-only array of bytes that contains the EDID\r | |

| 38 | NULL if no EDID information is available for the video output\r | |
| 39 | device. The minimum size of a valid Edid buffer is 128 bytes.\r | |
| 40 | EDID information is defined in the E-DID EEPROM\r | |
