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?
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".
