you can write a program such as:
int main(int argc, char **argv)
{
for (int i = 0; i < argc, i++)
{
printf("%s\n", argv[i]);
}
return 0;
}
compile and replace your daemon, run lmgrd, you can get what you want.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

but it didnot work . I paste it below , please have a look the let me know ?
step used :
(1) run lmgrd and get -T 10.1.4.238 8.4 3 -c magma.lic --lmgrd_start 42c34512
(2) gdb daemon
(3) run -T 10.1.4.238 8.4 3 -c magma.lic

You can't do that without a process to debug.

The program has no registers now.
