[bluetooth-dev] Some more coding questions???


well it has been a long day at work today, and i am tired, but before i go, i
have a question that could use an answer...

well, i am trying to figure out how the axis stack was coded, and how it
relates to the GAP (general access profile), anyways, here is my
question...in the btd.c file when you execute the command rf_conn, it will then
execute bt_connect, which intern will call an ioctl call...the parameters
passed are bd_fd, BTCONNECT, bt_connection; now i am curious about the
BTCONNECT, and where it comes from.  I noticed that in the btcommon.h file that
there is the BTCONNECT macro, but then the replacement text is _IOW....., where
does this _IOW come from and what does it do and mean???
