3 * pl_syscalls.d - count Perl subroutine calls and syscalls using DTrace.
4 *                 Written for the Perl DTrace provider.
5 *
6 * $Id: pl_syscalls.d 25 2007-09-12 09:51:58Z brendan $
7 *
8 * USAGE: pl_syscalls.d { -p PID | -c cmd }	# hit Ctrl-C to end
9 *
10 * FIELDS:
11 *		FILE		Filename of the Perl program
12 *		TYPE		Type of call (sub/syscall)
13 *		NAME		Name of call
14 *		COUNT		Number of calls during sample
15 *
16 * Filename and subroutine names are printed if available.
17 * The filename for syscalls may be printed as "perl", if the program
18 * was invoked using the form "perl filename" rather than running the
19 * program with an interpreter line.
