62/* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
63
64Defining PERL_OBJECT turns on creation of a C++ object that
65contains all writable core perl global variables and functions.
66Stated another way, all necessary global variables and functions
67are members of a big C++ object. This object's class is CPerlObj.
68This allows a Perl Host to have multiple, independent perl
69interpreters in the same process space. This is very important on
70Win32 systems as the overhead of process creation is quite high --
71this could be even higher than the script compile and execute time
72for small scripts.
73
74The perl executable implementation on Win32 is composed of perl.exe
75(the Perl Host) and perlX.dll. (the Perl Core). This allows the
76same Perl Core to easily be embedded in other applications that use
77the perl interpreter.

87+-----------+ +-----------+ ...
88
89Defining PERL_OBJECT has the following effects:
90
91PERL CORE
921. CPerlObj is defined (this is the PERL_OBJECT)
932. all static functions that needed to access either global
94variables or functions needed are made member functions
953. all writable static variables are made member variables
964. all global variables and functions are defined as:
22c35a8c 97 #define var CPerlObj::PL_var
3dfd1da1 98 #define func CPerlObj::Perl_func
22c35a8c 99 * these are in embed.h
3dfd1da1 100This necessitated renaming some local variables and functions that
101had the same name as a global variable or function. This was
102probably a _good_ thing anyway.
103
104
105EXTENSIONS
1061. Access to global variables and perl functions is through a
107pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
108made transparent to extension developers by the following macros:
22c35a8c 109 #define var pPerl->PL_var
3dfd1da1 110 #define func pPerl->Perl_func
6de196ee 111 * these are done in objXSUB.h
3dfd1da1 112This requires that the extension be compiled as C++, which means
113that the code must be ANSI C and not K&R C. For K&R extensions,
114please see the C API notes located in Win32/GenCAPI.pl. This script
6de196ee 115creates a perlCAPI.lib that provides a K & R compatible C interface
3dfd1da1 116to the PERL_OBJECT.
1172. Local variables and functions cannot have the same name as perl's
118variables or functions since the macros will redefine these. Look for
119this if you get some strange error message and it does not look like
120the code that you had written. This often happens with variables that
121are local to a function.
122
123PERL HOST
1241. The perl host is linked with perlX.lib to get perl_alloc. This
125function will return a pointer to CPerlObj (the PERL_OBJECT). It
0f4eea8f 126takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
127for more information on this).
3dfd1da1 1282. The perl host calls the same functions as normally would be
129called in setting up and running a perl script, except that the
130functions are now member functions of the PERL_OBJECT.
