[hpoj-devel] [patch] 0.9.7: fix LPGETSTATUS call

[Tim W. <tw...@re...>]

Hi,

Here is a patch to fix the storage size of the variable provided to
accept the data from the LPGETSTATUS ioctl.  This control returns
sizeof(int) bytes.

The symptom that lead me to investigate this was that hpiod was
send()ing "" -- the res variable was getting overwritten with zeros.

Tim.
