Subject: oops? read/write vs type of length parameter
Date: Mon, 11 Apr 2011 10:55:35 +0200 [thread overview]
Message-ID: <87wrj1jhfc.fsf@rho.meyering.net> (raw)
Hi Eli,
In http://bzr.savannah.gnu.org/lh/emacs/trunk/revision/103883
you adjusted the signatures of emacs_read and emacs_write.
- extern int emacs_read (int, char *, unsigned int);
- extern int emacs_write (int, const char *, unsigned int);
+ extern ssize_t emacs_read (int, char *, ssize_t);
+ extern ssize_t emacs_write (int, const char *, ssize_t);
It's good to see that you corrected the return type to be wider
(ssize_t) and still signed, just like "int".
However, did you really intend to make the buffer length parameters signed?
I would have expected those to be of type size_t, not ssize_t.
