       callgrind_control - observe and control programs being run by Callgrind

       callgrind_control [options] [pid|program-name...]

       callgrind_control controls programs being run by the Valgrind tool
       Callgrind. When a pid/program name argument is not specified, all
       applications currently being run by Callgrind on this system will be
       used for actions given by the specified option(s). The default action
       is to give some brief information about the applications being run by

       -h --help
	   Show a short description, usage, and summary of options.

	   Show version of callgrind_control.

       -l --long
	   Show also the working directory, in addition to the brief
	   information given by default.

       -s --stat
	   Show statistics information about active Callgrind runs.

       -b --back
	   Show stack/back traces of each thread in active Callgrind runs. For
	   each active function in the stack trace, also the number of
	   invocations since program start (or last dump) is shown. This
	   option can be combined with -e to show inclusive cost of active

       -e [A,B,...]  (default: all)
	   Show the current per-thread, exclusive cost values of event
	   counters. If no explicit event names are given, figures for all
	   event types which are collected in the given Callgrind run are
	   shown. Otherwise, only figures for event types A, B, ... are shown.
	   If this option is combined with -b, inclusive cost for the
	   functions of each active stack frame is provided, too.

       --dump[=<desc>]	(default: no description)
	   Request the dumping of profile information. Optionally, a
	   description can be specified which is written into the dump as part
	   of the information giving the reason which triggered the dump
	   action. This can be used to distinguish multiple dumps.

       -z --zero
	   Zero all event counters.

       -k --kill
	   Force a Callgrind run to be terminated.

	   Switch instrumentation mode on or off. If a Callgrind run has
	   instrumentation disabled, no simulation is done and no events are
	   counted. This is useful to skip uninteresting program parts, as
	   there is much less slowdown (same as with the Valgrind tool
	   "none"). See also the Callgrind option --instr-atstart.

	   Specify the startup directory of an active Callgrind run. On some
	   systems, active Callgrind runs can not be detected. To be able to
	   control these, the failed auto-detection can be worked around by
	   specifying the directory where a Callgrind run was started.
