Subject: what meaning of command function return val
Date: Tue, 4 Dec 2012 10:54:54 +0800 [thread overview]
Message-ID: <20121204025454.GC20812@greatfirst.com> (raw)
When write a command function do_xxx.
When all right it should return zero.
But when error, It should return a negtive value or a positive value?
And what difference between neg-val and pos-val?
