Subject: bugfix of error handling while open()
X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=cac289316bed4282f798dbe710398e6f53f66f1f;hp=3283d681f9da65b500ad0cb3d4550cb840ed481a;p=project%2Fprocd.git

bugfix of error handling while open()

The normal return value from open() is a non-negative integer.
In the case of an error, a value of -1 is returned instead.
