CALLGRIND CONTROL(1)			  Release 3.9.0 		     CALLGRIND CONTROL(1)

NAME
       callgrind_control - observe and control programs being run by Callgrind

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

DESCRIPTION
       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
       Callgrind.

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

       --version
	   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 functions.

       -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.

       --instr=<on|off>
	   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.

       -w=<dir>
	   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.
