I am interested to know where in source code the raw I/O is handled. I
guess that when you write something like open("/dev/r<foo>",flag) instead
of open("/dev/<foo>",flag), raw I/O happens. Can anyone tell me which
soure code files or routines handle RAW I/O? How to get the dev argument
to a device read() routine like wdopen() in wd.c?
Any help is appreciated.
