When scanning the code concerning STREAMS on SYSV.3.2 I noticed that I can do something to get in my multiplexor driver a notification from the streams head when a read is done on that stream. To get such a notification, the multiplexor can send an M_SETOPTS message to the streams head with the field 'so_flags' set to SO_MREADON. When this has been set the streams head will send an M_READ message to my driver at the time a process will perform a read on that stream. But, this feature is not documented. In the tutorials of SYSV.4, the M_READ message still exists in an include file, but nothing else concerning this option is mentioned. Does anybody know about this read notification on STREAMS? I would like to know if it works at the moment and if this feature also exists in further releases of SYSV. When this works I would also know if I understood the working of this feature correct.
