Hi, Michael and list!
I found two problems in the man pages. The first one should
be a bug. It is that the type of the 2nd and 4th arguments
of splice(2) is wrong. The current prototype of splice(2)
in current man page is:
long splice(int fd_in, off_t *off_in, int fd_out,
off_t *off_out, size_t len, unsigned int flags);
However, they should be 'loff_t' instead of 'off_t'. If we
use 'off_t', gcc will generate a warning. Patch is in the end
of this email and it's against 2.76 release. ;)
The second one is a bit confused. The example given in tee(2)
even can not run normally. I got this error:
$ ./example bar.txt
tee: Invalid argument
I looked at tee(2), it is said that:
EINVAL fd_in or fd_out does not refer to a pipe; or fd_in and fd_out
refer to the same pipe.
So the first two arguments of tee(2) in the example is wrong,
since neither STDIN_FILENO nor STDOUT_FILENO refers to a pipe.
But I am not so sure, because I am new to tee(2). ;) If you can
comfirm this is really a bug, I can send a patch to fix this too.
I have checked the newest release of man pages and my kernel version
is 2.6.21-1.3194.fc7. Did I miss something obvious?
(And please Cc me as I am not in the list.)
Thank you!
