From 7008e1086961f61ca26365b2b7500132ab98658d Mon Sep 17 00:00:00 2001 From: Martin Kletzander Date: Wed, 5 Apr 2017 16:13:52 +0200 Subject: [PATCH] util: Remove virsysfs and instead enhance virFileReadValue* functions It is no longer needed thanks to the great virfilewrapper.c. And this way we don't have to add a new set of functions for each prefixed path. While on that, add two functions that weren't there before, string and scaled integer reading ones. Also increase the length of the string being read by one to accompany for the optional newline at the end (i.e. change INT_STRLEN_BOUND to INT_BUFSIZE_BOUND).
