Hello,
I have the fllowing prog which leaks. I removed all the irrelevant parts.
Different functions call lead to memory leaks :
#include <stdlib.h>
#include <stdio.h>
#include <libgtop-2.0/glibtop.h>
#include <libgtop-2.0/glibtop/netload.h>
#include <libgtop-2.0/glibtop/close.h>
int main(int argc, char ** argv){
glibtop_init();
/* GET NET USAGE */
glibtop_netload buf;
const char interface[] = "wlan0";
glibtop_get_netload(&buf, interface);
printf("NETWORK :%lu %lu\n", buf.packets_in, buf.packets_out);
// Just in case
g_free(&buf);
glibtop_close();
return 0;
}
and valgrind reports:
