NAME

       AEServer

       AEServer(8) -- System-wide daemon which recevies incoming (remote) AppleEvents

DESCRIPTION

       AEServer  acts  as a system-wide daemon when Remote AppleEvents is enabled, allowing other computers to send AppleEvents to applications on
       this machine.

NAME

       dylibprof - control the shared pc sampling of a dynamic shared library

SYNOPSIS

       dylibprof [-e | -d] | [-c | -r | -b | -h | -p [-o <file>] <dylib>]

DESCRIPTION

       Dylibprof  along  with  the server /usr/libexec/profileServer allows shared program counter sampling of a dynamic shared library across all
       the programs that use the library.

       To use dylibprof(1), /usr/libexec/profileServer must be running.  So first start /usr/libexec/profileServer and leave  it  running  in  the
       back ground:
	    % /usr/libexec/profileServer >& /dev/console &

       /usr/libexec/profileServer starts up with shared pc sampling disabled.  It should not be left running with shared pc sampling enabled if no
       sampling is being done as every launch of a program that uses the dynamic linker is effected.  This is true even to a small extent if there
       no libraries being sampled.

       If you need to profile from boot up for all processes then the following line can be added to /etc/bootstrap.conf:
	    server "/usr/libexec/profileServer" services NSProfileServer NSProfileControl;

       Before any dynamic shared library can be sampled sampling must be enabled as
       follows:
	    % dylibprof -e

       It can then later be disabled when no more sampling is to be done with:
	    % dylibprof -d

EXAMPLE

       To  sample  the	dynamic  shared  library  /System/Library/Frameworks/System.framework/Versions/B/System for example requires the following
       steps.  First create a sample buffer for the library:
	    % dylibprof -c /System/Library/Frameworks/System.framework/Versions/B/System

       Then begin the sampling:
	    % dylibprof -b /System/Library/Frameworks/System.framework/Versions/B/System
       After this programs launched using this library will be part of the shared pc sampling.	Typically what would be done is to  then  use  the
       system normally for a number of hours.

       Then to halt the sampling:
	    % dylibprof -h /System/Library/Frameworks/System.framework/Versions/B/System

       The profiling output file (a gmon.out file) can be created with:
	    % dylibprof -p -o /tmp/gmon.out /System/Library/Frameworks/System.framework/Versions/B/System

       Using the profiling output file and the library a profile listing and a time based order file (time.order) can be created with: gprof(1):
	    % gprof -S /System/Library/Frameworks/System.framework/Versions/B/System /tmp/gmon.out

       When no more sampling for this library is to be done the sample buffer can be
       removed with:
	    % dylibprof -r /System/Library/Frameworks/System.framework/Versions/B/System

       The options are:

       -e     Enable shared program counter sampling for dynamic libraries.

       -d     Disable shared program counter sampling for dynamic libraries.

       -c     Create a pc sample buffer for the library.

       -b     Begin sampling for programs subsequently launched using the library.

       -h     Halt sampling for programs subsequently launched using the library.

       -p     Produce a profiling output file (a gmon.out file) for the library.

       -r     Remove the pc sample buffer for the library.

       -o name
	      Use the file name instead of gmon.out when producing the profiling output file with the -p above.
