Subject: [RFC][4/11][MANUX] Kernel compatibility : ioctl(2)
Date: Tue, 15 Apr 2014 15:42:54 +0200 [thread overview]
Message-ID: <534D375E.7070308@manux.info> (raw)
Continuing with syscalls, I would like to indicate you a modification
I've done with regards to ioctl's. The thing is, I have had the need for
ioctl's that return *file descriptors*, instead of standard return codes.
To distinguish them from the others, I have given them identifiers that
are superior or equal to 0x80000000 (when unsigned, negative when
signed). Of course, Linux will reject them, but that's fine, these are
low-level OS-dependant ioctl's that aren't supposed to be compatible.
Do you have any objection or remark regarding this?
Thanks!
Emmanuel
