- /* 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 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.
