I recently bought the SVR4 DDI/DKI reference manual. In looking through the migration info from SVR3.2, it says there is no equivalent to signal and psignal. How then does a device driver send a signal to a process? As a second, less important question, it also says that mmap will not be supported after 4.0, but gives no clue as to a replacement. I would assume that all of the code which calls memmap will have to interrogate the driver in some driver-dependent way to get a physical address and then use shmget to access it. I would hope there is another way, since this is pretty ugly. Thanks for any help. -- John Tamplin Xavax jat@xavax.COM 2104 West Ferry Way ...!uunet!xavax!jat Huntsville, AL 35801
