README 

Perf-Trace-Util version 0.01
============================

This module contains utility functions for use with perf script.

Core.pm and Util.pm are pure Perl modules; Core.pm contains routines
that the core perf support for Perl calls on and should always be
'used', while Util.pm contains useful but optional utility functions
that scripts may want to use.  Context.pm contains the Perl->C
interface that allows scripts to access data in the embedding perf
executable; scripts wishing to do that should 'use Context.pm'.

The Perl->C perf interface is completely driven by Context.xs.  If you
want to add new Perl functions that end up accessing C data in the
perf executable, you add desciptions of the new functions here.
scripting_context is a pointer to the perf data in the perf executable
that you want to access - it's passed as the second parameter,
$context, to all handler functions.

After you do that:

  perl Makefile.PL   # to create a Makefile for the next step
  make               # to create Context.c

  edit Context.c to add const to the char* file = __FILE__ line in
  XS(boot_Perf__Trace__Context) to silence a warning/error.

  You can delete the Makefile, object files and anything else that was
  generated e.g. blib and shared library, etc, except for of course
  Context.c

  You should then be able to run the normal perf make as usual.

INSTALLATION

Building perf with perf script Perl scripting should install this
module in the right place.

You should make sure libperl and ExtUtils/Embed.pm are installed first
e.g. apt-get install libperl-dev or yum install perl-ExtUtils-Embed.
