80 /* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
82 Defining PERL_OBJECT turns on creation of a C++ object that
83 contains all writable core perl global variables and functions.
84 Stated another way, all necessary global variables and functions
85 are members of a big C++ object. This object's class is CPerlObj.
86 This allows a Perl Host to have multiple, independent perl
87 interpreters in the same process space. This is very important on
88 Win32 systems as the overhead of process creation is quite high --
89 this could be even higher than the script compile and execute time
92 The perl executable implementation on Win32 is composed of perl.exe
93 (the Perl Host) and perlX.dll. (the Perl Core). This allows the
94 same Perl Core to easily be embedded in other applications that use
103 +-----------+ +-----------+
104 | Perl Core |<->| Extension |
105 +-----------+ +-----------+ ...
107 Defining PERL_OBJECT has the following effects:
110 1. CPerlObj is defined (this is the PERL_OBJECT)
111 2. all static functions that needed to access either global
112 variables or functions needed are made member functions
113 3. all writable static variables are made member variables
114 4. all global variables and functions are defined as:
115 #define var CPerlObj::PL_var
116 #define func CPerlObj::Perl_func
117 * these are in embed.h
118 This necessitated renaming some local variables and functions that
119 had the same name as a global variable or function. This was
120 probably a _good_ thing anyway.
124 1. Access to global variables and perl functions is through a
125 pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
126 made transparent to extension developers by the following macros:
127 #define var pPerl->PL_var
128 #define func pPerl->Perl_func
129 * these are done in objXSUB.h
130 This requires that the extension be compiled as C++, which means
131 that the code must be ANSI C and not K&R C. For K&R extensions,
132 please see the C API notes located in Win32/GenCAPI.pl. This script
133 creates a perlCAPI.lib that provides a K & R compatible C interface
135 2. Local variables and functions cannot have the same name as perl's
136 variables or functions since the macros will redefine these. Look for
137 this if you get some strange error message and it does not look like
138 the code that you had written. This often happens with variables that
139 are local to a function.
142 1. The perl host is linked with perlX.lib to get perl_alloc. This
143 function will return a pointer to CPerlObj (the PERL_OBJECT). It
144 takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
145 for more information on this).
146 2. The perl host calls the same functions as normally would be
147 called in setting up and running a perl script, except that the
148 functions are now member functions of the PERL_OBJECT.
