82/* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
83
84Defining PERL_OBJECT turns on creation of a C++ object that
85contains all writable core perl global variables and functions.
86Stated another way, all necessary global variables and functions
87are members of a big C++ object. This object's class is CPerlObj.
88This allows a Perl Host to have multiple, independent perl
89interpreters in the same process space. This is very important on
90Win32 systems as the overhead of process creation is quite high --
91this could be even higher than the script compile and execute time
92for small scripts.
93
94The perl executable implementation on Win32 is composed of perl.exe
95(the Perl Host) and perlX.dll. (the Perl Core). This allows the
96same Perl Core to easily be embedded in other applications that use
97the perl interpreter.

107+-----------+ +-----------+ ...
108
109Defining PERL_OBJECT has the following effects:
110
111PERL CORE
1121. CPerlObj is defined (this is the PERL_OBJECT)
1132. all static functions that needed to access either global
114variables or functions needed are made member functions
1153. all writable static variables are made member variables
1164. all global variables and functions are defined as:
22c35a8c 117 #define var CPerlObj::PL_var
3dfd1da1 118 #define func CPerlObj::Perl_func
22c35a8c 119 * these are in embed.h
3dfd1da1
GS		 120This necessitated renaming some local variables and functions that
121had the same name as a global variable or function. This was
122probably a _good_ thing anyway.
123
124
125EXTENSIONS
1261. Access to global variables and perl functions is through a
127pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
128made transparent to extension developers by the following macros:
22c35a8c 129 #define var pPerl->PL_var
3dfd1da1 130 #define func pPerl->Perl_func
6de196ee 131 * these are done in objXSUB.h
3dfd1da1
GS		 132This requires that the extension be compiled as C++, which means
133that the code must be ANSI C and not K&R C. For K&R extensions,
134please see the C API notes located in Win32/GenCAPI.pl. This script
6de196ee 135creates a perlCAPI.lib that provides a K & R compatible C interface
3dfd1da1
GS		 136to the PERL_OBJECT.
1372. Local variables and functions cannot have the same name as perl's
138variables or functions since the macros will redefine these. Look for
139this if you get some strange error message and it does not look like
140the code that you had written. This often happens with variables that
141are local to a function.
142
143PERL HOST
1441. The perl host is linked with perlX.lib to get perl_alloc. This
145function will return a pointer to CPerlObj (the PERL_OBJECT). It
0f4eea8f
DL		 146takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
147for more information on this).
3dfd1da1
GS		 1482. The perl host calls the same functions as normally would be
149called in setting up and running a perl script, except that the
150functions are now member functions of the PERL_OBJECT.
