Subject: change type of result variables to ssize_t
X-Git-Url: http://sigrok.org/gitweb/?p=libserialport.git;a=commitdiff_plain;h=fd20b0fc5a34cd7f776e4af6c763f59041de223b

change type of result variables to ssize_t

These variables are being used to store the result of read/write calls,
which return a ssize_t value, which depending on platform can be bigger
than an int.
