private connection seems always cause a memory leak
run this demo:
#include <stdio.h>
#include <unistd.h>
#include <dbus/dbus.h>
void test()
{
DBusConnection *dbus_conn = dbus_bus_get_private(DBUS_BUS_SESSION, NULL);
dbus_connection_close(dbus_conn);
dbus_connection_unref(dbus_conn);
}
int main()
{
int nIndex = 0;
while(TRUE)
{
printf("Test %d times\n", ++nIndex);
test();
usleep(100);
}
return 0;
