I am trying to use dtrace to trace all sscanf calls. I am able to use pid provider for this. But my application forks off children at times to handle requests. Is there a way I can stop the child process immediately after it is started so that I can attach a pid provider to that and trace the scanf calls in it? I have tried using the "create" probe but that did not help.

In crossbow, each mac_srs has a kernel thread called "mac_rx_srs_poll_ring" to poll the hardware and crossbow will wakeup this thread to poll packets from the hardware automatically. Does crossbow provide any method to disable the polling mechanism, for example disabling the this kernel thread?
