86 /* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
88 Defining PERL_OBJECT turns on creation of a C++ object that
89 contains all writable core perl global variables and functions.
90 Stated another way, all necessary global variables and functions
91 are members of a big C++ object. This object's class is CPerlObj.
92 This allows a Perl Host to have multiple, independent perl
93 interpreters in the same process space. This is very important on
94 Win32 systems as the overhead of process creation is quite high --
95 this could be even higher than the script compile and execute time
98 The perl executable implementation on Win32 is composed of perl.exe
99 (the Perl Host) and perlX.dll. (the Perl Core). This allows the
100 same Perl Core to easily be embedded in other applications that use
101 the perl interpreter.
109 +-----------+ +-----------+
110 | Perl Core |<->| Extension |
111 +-----------+ +-----------+ ...
113 Defining PERL_OBJECT has the following effects:
116 1. CPerlObj is defined (this is the PERL_OBJECT)
117 2. all static functions that needed to access either global
118 variables or functions needed are made member functions
119 3. all writable static variables are made member variables
120 4. all global variables and functions are defined as:
121 #define var CPerlObj::PL_var
122 #define func CPerlObj::Perl_func
123 * these are in embed.h
124 This necessitated renaming some local variables and functions that
125 had the same name as a global variable or function. This was
126 probably a _good_ thing anyway.
130 1. Access to global variables and perl functions is through a
131 pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
132 made transparent to extension developers by the following macros:
133 #define var pPerl->PL_var
134 #define func pPerl->Perl_func
135 * these are done in objXSUB.h
136 This requires that the extension be compiled as C++, which means
137 that the code must be ANSI C and not K&R C. For K&R extensions,
138 please see the C API notes located in Win32/GenCAPI.pl. This script
139 creates a perlCAPI.lib that provides a K & R compatible C interface
141 2. Local variables and functions cannot have the same name as perl's
142 variables or functions since the macros will redefine these. Look for
143 this if you get some strange error message and it does not look like
144 the code that you had written. This often happens with variables that
145 are local to a function.
148 1. The perl host is linked with perlX.lib to get perl_alloc. This
149 function will return a pointer to CPerlObj (the PERL_OBJECT). It
150 takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
151 for more information on this).
152 2. The perl host calls the same functions as normally would be
153 called in setting up and running a perl script, except that the
154 functions are now member functions of the PERL_OBJECT.
