From 8d38d74b648513dd8ed8bd2b67d899208ef4e09e Mon Sep 17 00:00:00 2001 From: Chen Gong Date: Mon, 16 May 2011 10:58:57 -0700 Subject: pstore: fix one type of return value in pstore the return type of function _read_ in pstore is size_t, but in the callback function of _read_, the logic doesn't consider it too much, which means if negative value (assuming error here) is returned, it will be converted to positive because of type casting. ssize_t is enough for this function.
