61 ``start_block`` and of size ``blocks`` will be placed in the memory
63 ``blocks`` * 128 bytes large (the size of one block is 128 bytes).
65 If there are fewer blocks than specified, then the driver will set
66 ``blocks`` to the actual number of blocks. If there are no EDID blocks
69 If blocks have to be retrieved from the sink, then this call will block
72 If ``start_block`` and ``blocks`` are both set to 0 when
73 :ref:`VIDIOC_G_EDID <VIDIOC_G_EDID>` is called, then the driver will set ``blocks`` to the
74 total number of available EDID blocks and it will return 0 without
75 copying any data. This is an easy way to discover how many EDID blocks
