CALLGRIND 
CONTROL(1)						   Release 3.7.0					      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.
