Hi at all, I would to have some additional infos about pix_share_write and pix_share_read objects... i would to know what mean "shared memory region", is this the video card frame buffer or the RAM? and what mean the ID field (how many id can i use? how can i calculate shared memory dimension and maximum ID?)
Thank you for the help and excuse for my bad english :-)

it refers to "POSIX shared memory objects" or equivalent (thus RAM)
and what mean the ID field (how many id can i use? how can i calculate shared memory dimension and maximum ID?)
ID is an identifier for the shared-memory. the important thing to know is, that both [pix_share_read] and [pix_share_write] need to use the same ID, in order to access the same piece of memory. i would recommend to use values that are covered by "unsigned short".
