static long	OPTION_EXEC Return the bitmask for enabling exec tracing.
static long	OPTION_EXIT Return the bitmask for enabling exit tracing.
static long	OPTION_FORK Return the bitmask for enabling fork tracing.
static long	OPTION_SYSGOOD Return the bitmask for enabling SYSGOOD(?} tracing.

Constructor Summary

Ptrace()

Method Summary

static void	attach(ProcessIdentifier pid) Attach to the process specified by PID.
static void	cont(ProcessIdentifier pid, Signal signal) Continue the process specified by PID, if SIG is non-zero, deliver the signal.
static void	detach(ProcessIdentifier pid, Signal signal) Detach from the process specified by PID.
static long	getEventMsg(ProcessIdentifier pid) Fetch the auxilary information associated with PID's last WAIT event.
static void	setOptions(ProcessIdentifier pid, long options) Set PID's trace options.
static void	singleStep(ProcessIdentifier pid, Signal signal) Single-step (instruction step) the process specified by PID, if SIG is non-zero, deliver the signal.
static void	sysCall(ProcessIdentifier pid, Signal signal) Continue the process specified by PID, stopping when there is a system-call; if SIG is non-zero deliver the signal.

Method Detail

attach

public static void attach(ProcessIdentifier pid)

Attach to the process specified by PID.

detach

public static void detach(ProcessIdentifier pid,
                          Signal signal)

Detach from the process specified by PID.

singleStep

public static void singleStep(ProcessIdentifier pid,
                              Signal signal)

Single-step (instruction step) the process specified by PID, if SIG is non-zero, deliver the signal.

cont

public static void cont(ProcessIdentifier pid,
                        Signal signal)

Continue the process specified by PID, if SIG is non-zero, deliver the signal.

sysCall

public static void sysCall(ProcessIdentifier pid,
                           Signal signal)

Continue the process specified by PID, stopping when there is a system-call; if SIG is non-zero deliver the signal.

getEventMsg

public static long getEventMsg(ProcessIdentifier pid)

Fetch the auxilary information associated with PID's last WAIT event.

setOptions

public static void setOptions(ProcessIdentifier pid,
                              long options)

Set PID's trace options. OPTIONS is formed by or'ing the values returned by the option* methods below.
