Hi When looking at the rtdm examples tut01-skeleton en tut02-skeleton, I have a question about the context_size in the rtdm_device struct.
In tut01-skeleton-drv.c, the context_size = sizeof(buffer_t), in the other example context_size = 0. Both drivers uses the rtdm_safe_copy_to_user/rtdm_safe_copy_from_user functions to write/read data from buffer_t(kernel space) to user_space. So I don't understand why the context_size in tut02 is different than in tut01. Or is the context_size only important if we open the driver several times from one or more user_space programs? Thanks in advance Steven
