exit

Stops all tracing and exits to return an exit value.

void exit(int status)

The exit function is used to immediately stop tracing and inform DTrace to do the following: stop tracing, perform any final processing, and call exit() with the specified status value. Because exit returns a status to user level, it's considered a data recording function. However, unlike other data recording functions, exit can't be speculatively traced. Note that because exit is a data recording function, it can be dropped.

When exit is called, only those DTrace functions that are already in progress on other CPUs are completed. No new functions occur on any CPU. The only exception to this rule is the processing of the END probe, which is called after the DTrace has processed the exit function, and indicates that tracing must stop.
