Hi,

I use the system call and it seems to work ok (mdpsim is the name
of my module). I don't know about inserting the module - need root
privileges.


int ret;

ret = system("/sbin/lsmod | grep ^mdpsim");

if (ret == 127) {
  fl_addto_browser(fd_control_form->connect_form_browser,"/bin/sh failed");
  return;
}
if (ret != 0) {
  fl_addto_browser(fd_control_form->connect_form_browser,"mdpsim.o not installed");
  return;
}
fprintf(stderr,"System return = %d\n",ret);

Cheers,
Matt W
