; parasite_trap_cmd(int cmd, void *arg);
−
int main(void *arg_p, unsigned int arg_s);

that should be present in your code. The <code>arg_p</code> and <code>arg_s</code> is the binary argument that will get delivered to parasite code by complel <code>_start()</code> call (see below). Sometimes this binary argument can be treated as CLI arguments argc/argv.
+
; parasite_daemon_cmd(int cmd, void *arg);
 +
: This routine gets called by <code>compel_rpc_call()</code> and <code>compel_rpc_call_sync()</code>
