80/* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
81
82Defining PERL_OBJECT turns on creation of a C++ object that
83contains all writable core perl global variables and functions.
84Stated another way, all necessary global variables and functions
85are members of a big C++ object. This object's class is CPerlObj.
86This allows a Perl Host to have multiple, independent perl
87interpreters in the same process space. This is very important on
88Win32 systems as the overhead of process creation is quite high --
89this could be even higher than the script compile and execute time
90for small scripts.
91
92The perl executable implementation on Win32 is composed of perl.exe
93(the Perl Host) and perlX.dll. (the Perl Core). This allows the
94same Perl Core to easily be embedded in other applications that use
95the perl interpreter.

105+-----------+ +-----------+ ...
106
107Defining PERL_OBJECT has the following effects:
108
109PERL CORE
1101. CPerlObj is defined (this is the PERL_OBJECT)
1112. all static functions that needed to access either global
112variables or functions needed are made member functions
1133. all writable static variables are made member variables
1144. all global variables and functions are defined as:
22c35a8c 115 #define var CPerlObj::PL_var
3dfd1da1 116 #define func CPerlObj::Perl_func
22c35a8c 117 * these are in embed.h
3dfd1da1 118This necessitated renaming some local variables and functions that
119had the same name as a global variable or function. This was
120probably a _good_ thing anyway.
121
122
123EXTENSIONS
1241. Access to global variables and perl functions is through a
125pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
126made transparent to extension developers by the following macros:
22c35a8c 127 #define var pPerl->PL_var
3dfd1da1 128 #define func pPerl->Perl_func
6de196ee 129 * these are done in objXSUB.h
3dfd1da1 130This requires that the extension be compiled as C++, which means
131that the code must be ANSI C and not K&R C. For K&R extensions,
132please see the C API notes located in Win32/GenCAPI.pl. This script
6de196ee 133creates a perlCAPI.lib that provides a K & R compatible C interface
3dfd1da1 134to the PERL_OBJECT.
1352. Local variables and functions cannot have the same name as perl's
136variables or functions since the macros will redefine these. Look for
137this if you get some strange error message and it does not look like
138the code that you had written. This often happens with variables that
139are local to a function.
140
141PERL HOST
1421. The perl host is linked with perlX.lib to get perl_alloc. This
143function will return a pointer to CPerlObj (the PERL_OBJECT). It
0f4eea8f 144takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
145for more information on this).
3dfd1da1 1462. The perl host calls the same functions as normally would be
147called in setting up and running a perl script, except that the
148functions are now member functions of the PERL_OBJECT.
