Subject: Calling ioctl_ptr
Date: Thu, 29 Feb 1996 12:19:36 -0800 (PST) [thread overview]
Message-ID: <199602292019.MAA03081@owl.vlibs.com> (raw)
Bonjour,
I need to explicitly manipulate modem/rs-232 control lines on a 32 bit
sun-0s4.1 system. I was going to invoke ioctl_ptr to do the job.
The first argument to ioctl_ptr is an int. The bits which determine a
modem control line request are 30 and 31. Is there a trick I can use
to set only bit 30 and not 31 and vice-versa?
If no trick is available I will write my own
ioctlx_ptr: file_descr -> string -> string -> int
-cheers
