This subsection describes ROCGDB commands specific to the GNU Hurd native debugging.
set signals ¶set sigsThis command toggles the state of inferior signal interception by
ROCGDB. Mach exceptions, such as breakpoint traps, are not
affected by this command. sigs is a shorthand alias for
signals.
show signals ¶show sigsShow the current state of intercepting inferior’s signals.
set signal-thread ¶set sigthreadThis command tells ROCGDB which thread is the libc signal
thread. That thread is run when a signal is delivered to a running
process. set sigthread is the shorthand alias of set
signal-thread.
show signal-thread ¶show sigthreadThese two commands show which thread will run when the inferior is delivered a signal.
set stopped ¶This commands tells ROCGDB that the inferior process is stopped,
as with the SIGSTOP signal. The stopped process can be
continued by delivering a signal to it.
show stopped ¶This command shows whether ROCGDB thinks the debuggee is stopped.
set exceptions ¶Use this command to turn off trapping of exceptions in the inferior. When exception trapping is off, neither breakpoints nor single-stepping will work. To restore the default, set exception trapping on.
show exceptions ¶Show the current state of trapping exceptions in the inferior.
set task pause ¶This command toggles task suspension when ROCGDB has control.
Setting it to on takes effect immediately, and the task is suspended
whenever ROCGDB gets control. Setting it to off will take
effect the next time the inferior is continued. If this option is set
to off, you can use set thread default pause on or set
thread pause on (see below) to pause individual threads.
show task pause ¶Show the current state of task suspension.
set task detach-suspend-count ¶This command sets the suspend count the task will be left with when ROCGDB detaches from it.
show task detach-suspend-countShow the suspend count the task will be left with when detaching.
set task exception-port ¶set task excpThis command sets the task exception port to which ROCGDB will
forward exceptions. The argument should be the value of the send
rights of the task. set task excp is a shorthand alias.
set noninvasive ¶This command switches ROCGDB to a mode that is the least
invasive as far as interfering with the inferior is concerned. This
is the same as using set task pause, set exceptions, and
set signals to values opposite to the defaults.
info send-rights ¶info receive-rightsinfo port-rightsinfo port-setsinfo dead-namesinfo portsinfo psetsThese commands display information about, respectively, send rights,
receive rights, port rights, port sets, and dead names of a task.
There are also shorthand aliases: info ports for info
port-rights and info psets for info port-sets.
set thread pause ¶This command toggles current thread suspension when ROCGDB has
control. Setting it to on takes effect immediately, and the current
thread is suspended whenever ROCGDB gets control. Setting it to
off will take effect the next time the inferior is continued.
Normally, this command has no effect, since when ROCGDB has
control, the whole task is suspended. However, if you used set
task pause off (see above), this command comes in handy to suspend
only the current thread.
show thread pause ¶This command shows the state of current thread suspension.
set thread runThis command sets whether the current thread is allowed to run.
show thread runShow whether the current thread is allowed to run.
set thread detach-suspend-count ¶This command sets the suspend count ROCGDB will leave on a
thread when detaching. This number is relative to the suspend count
found by ROCGDB when it notices the thread; use set thread
takeover-suspend-count to force it to an absolute value.
show thread detach-suspend-countShow the suspend count ROCGDB will leave on the thread when detaching.
set thread exception-portset thread excpSet the thread exception port to which to forward exceptions. This
overrides the port set by set task exception-port (see above).
set thread excp is the shorthand alias.
set thread takeover-suspend-countNormally, ROCGDB’s thread suspend counts are relative to the value ROCGDB finds when it notices each thread. This command changes the suspend counts to be absolute instead.
set thread default ¶show thread defaultEach of the above set thread commands has a set thread
default counterpart (e.g., set thread default pause, set
thread default exception-port, etc.). The thread default
variety of commands sets the default thread properties for all
threads; you can then change the properties of individual threads with
the non-default commands.
