/* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
Defining PERL_OBJECT turns on creation of a C++ object that
contains all writable core perl global variables and functions.
Stated another way, all necessary global variables and functions
are members of a big C++ object. This object's class is CPerlObj.
This allows a Perl Host to have multiple, independent perl
interpreters in the same process space. This is very important on
Win32 systems as the overhead of process creation is quite high --
this could be even higher than the script compile and execute time
for small scripts.
The perl executable implementation on Win32 is composed of perl.exe
(the Perl Host) and perlX.dll. (the Perl Core). This allows the
same Perl Core to easily be embedded in other applications that use
the perl interpreter.
+-----------+
| Perl Host |
+-----------+
^
|
v
+-----------+ +-----------+
| Perl Core |<->| Extension |
+-----------+ +-----------+ ...
Defining PERL_OBJECT has the following effects:
PERL CORE
1. CPerlObj is defined (this is the PERL_OBJECT)
2. all static functions that needed to access either global
variables or functions needed are made member functions
3. all writable static variables are made member variables
4. all global variables and functions are defined as:
#define var CPerlObj::PL_var
#define func CPerlObj::Perl_func
* these are in embed.h
This necessitated renaming some local variables and functions that
had the same name as a global variable or function. This was
probably a _good_ thing anyway.
EXTENSIONS
1. Access to global variables and perl functions is through a
pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
made transparent to extension developers by the following macros:
#define var pPerl->PL_var
#define func pPerl->Perl_func
* these are done in objXSUB.h
This requires that the extension be compiled as C++, which means
that the code must be ANSI C and not K&R C. For K&R extensions,
please see the C API notes located in Win32/GenCAPI.pl. This script
creates a perlCAPI.lib that provides a K & R compatible C interface
to the PERL_OBJECT.
2. Local variables and functions cannot have the same name as perl's
variables or functions since the macros will redefine these. Look for
this if you get some strange error message and it does not look like
the code that you had written. This often happens with variables that
are local to a function.
PERL HOST
1. The perl host is linked with perlX.lib to get perl_alloc. This
function will return a pointer to CPerlObj (the PERL_OBJECT). It
takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
for more information on this).
2. The perl host calls the same functions as normally would be
called in setting up and running a perl script, except that the
functions are now member functions of the PERL_OBJECT.
