72/* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
73
74Defining PERL_OBJECT turns on creation of a C++ object that
75contains all writable core perl global variables and functions.
76Stated another way, all necessary global variables and functions
77are members of a big C++ object. This object's class is CPerlObj.
78This allows a Perl Host to have multiple, independent perl
79interpreters in the same process space. This is very important on
80Win32 systems as the overhead of process creation is quite high --
81this could be even higher than the script compile and execute time
82for small scripts.
83
84The perl executable implementation on Win32 is composed of perl.exe
85(the Perl Host) and perlX.dll. (the Perl Core). This allows the
86same Perl Core to easily be embedded in other applications that use
87the perl interpreter.

97+-----------+ +-----------+ ...

99Defining PERL_OBJECT has the following effects:
100
101PERL CORE
1021. CPerlObj is defined (this is the PERL_OBJECT)
1032. all static functions that needed to access either global
104variables or functions needed are made member functions
1053. all writable static variables are made member variables
1064. all global variables and functions are defined as:
22c35a8c 107 #define var CPerlObj::PL_var
3dfd1da1 108 #define func CPerlObj::Perl_func
22c35a8c 109 * these are in embed.h
3dfd1da1
GS
110This necessitated renaming some local variables and functions that
111had the same name as a global variable or function. This was
112probably a _good_ thing anyway.
113
114
115EXTENSIONS
1161. Access to global variables and perl functions is through a
117pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
118made transparent to extension developers by the following macros:
22c35a8c 119 #define var pPerl->PL_var
3dfd1da1 120 #define func pPerl->Perl_func
6de196ee 121 * these are done in objXSUB.h
3dfd1da1
GS
122This requires that the extension be compiled as C++, which means
123that the code must be ANSI C and not K&R C. For K&R extensions,
124please see the C API notes located in Win32/GenCAPI.pl. This script
6de196ee 125creates a perlCAPI.lib that provides a K & R compatible C interface
3dfd1da1
GS
126to the PERL_OBJECT.
1272. Local variables and functions cannot have the same name as perl's
128variables or functions since the macros will redefine these. Look for
129this if you get some strange error message and it does not look like
130the code that you had written. This often happens with variables that
131are local to a function.
132
133PERL HOST
1341. The perl host is linked with perlX.lib to get perl_alloc. This
135function will return a pointer to CPerlObj (the PERL_OBJECT). It
0f4eea8f
DL
136takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
137for more information on this).
3dfd1da1
GS
1382. The perl host calls the same functions as normally would be
139called in setting up and running a perl script, except that the
140functions are now member functions of the PERL_OBJECT.
