I recently re-structured all the APIs in this file, to follow a
new coding style. This method would need to be updated to match.
{
virNodeCpuTime *stats = NULL;
int nr_stats, i;
int rv = -1;
if (args->maxStats > REMOTE_NODE_CPU_TIME_MAX) {
virNetError (VIR_ERR_INTERNAL_ERROR, "%s",
_("maxStats > REMOTE_NODE_CPU_TIME_MAX"));
goto cleanup;
}
/* Allocate stats array for making dispatch call */
if (VIR_ALLOC_N(stats, args->maxStats) < 0) {
virReportOOMError();
goto cleanup;
}
if ((nr_stats = virNodeGetCpuTime (conn, stats, args->maxStats, 0)) < 0)
goto cleanup;
/* Allocate return buffer */
if (VIR_ALLOC_N(ret->stats.stats_val, args->maxStats) < 0) {
virReportOOMError();
goto cleanup;
}
/* Copy the stats into the xdr return structure */
for (i = 0; i < nr_stats; i++) {
ret->stats.stats_val[i].tag = stats[i].tag;
ret->stats.stats_val[i].val = stats[i].val;
}
ret->stats.stats_len = nr_stats;
rv = 0;
cleanup:
if (rv < 0)
remoteDispatchError(rerr);
VIR_FREE(stats);
return rv;
}
Of course, if we change the public API as I suggest, it'll need a couple
more changes too.
Regards,
Daniel
