if (tid)
proc = g_strdup_printf("/proc/%d/task/%d/sched", (int) pid, (int)
tid);
else
proc = g_strdup_printf("/proc/%d/sched", (int) pid);
if (!proc)
return -1; <=== not reported
g_strdup_printf can't fail unless we mangled the printf format string
(which we havent), so that 'if (!proc)' check is redundant / unreachable
