4 * Written for the Python DTrace provider.
6 * $Id: py_syscalls.d 25 2007-09-12 09:51:58Z brendan $
8 * USAGE: py_syscalls.d { -p PID | -c cmd } # hit Ctrl-C to end
11 * FILE Filename of the Python program
12 * TYPE Type of call (func/syscall)
14 * COUNT Number of calls during sample
16 * Filename and function names are printed if available.
17 * The filename for syscalls may be printed as "python", if the program
18 * was invoked using the form "python filename" rather than running the
