Solaris Dynamic Tracing Guide


void stop(void)

The stop() action forces the process that fires the enabled probe to stop when it next leaves the kernel, as if stopped by a proc(4) action. The prun(1) utility may be used to resume a process that has been stopped by the stop() action. The stop() action can be used to stop a process at any DTrace probe point. This action can be used to capture a program in a particular state that would be difficult to achieve with a simple breakpoint, and then attach a traditional debugger like mdb(1) to the process. You can also use the gcore(1) utility to save the state of a stopped process in a core file for later analysis.
