73 /* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
75 Defining PERL_OBJECT turns on creation of a C++ object that
76 contains all writable core perl global variables and functions.
77 Stated another way, all necessary global variables and functions
78 are members of a big C++ object. This object's class is CPerlObj.
79 This allows a Perl Host to have multiple, independent perl
80 interpreters in the same process space. This is very important on
81 Win32 systems as the overhead of process creation is quite high --
82 this could be even higher than the script compile and execute time
85 The perl executable implementation on Win32 is composed of perl.exe
86 (the Perl Host) and perlX.dll. (the Perl Core). This allows the
87 same Perl Core to easily be embedded in other applications that use
96 +-----------+ +-----------+
97 | Perl Core |<->| Extension |
98 +-----------+ +-----------+ ...
100 Defining PERL_OBJECT has the following effects:
103 1. CPerlObj is defined (this is the PERL_OBJECT)
104 2. all static functions that needed to access either global
105 variables or functions needed are made member functions
106 3. all writable static variables are made member variables
107 4. all global variables and functions are defined as:
108 #define var CPerlObj::PL_var
109 #define func CPerlObj::Perl_func
110 * these are in embed.h
111 This necessitated renaming some local variables and functions that
112 had the same name as a global variable or function. This was
113 probably a _good_ thing anyway.
117 1. Access to global variables and perl functions is through a
118 pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
119 made transparent to extension developers by the following macros:
120 #define var pPerl->PL_var
121 #define func pPerl->Perl_func
122 * these are done in objXSUB.h
123 This requires that the extension be compiled as C++, which means
124 that the code must be ANSI C and not K&R C. For K&R extensions,
125 please see the C API notes located in Win32/GenCAPI.pl. This script
126 creates a perlCAPI.lib that provides a K & R compatible C interface
128 2. Local variables and functions cannot have the same name as perl's
129 variables or functions since the macros will redefine these. Look for
130 this if you get some strange error message and it does not look like
131 the code that you had written. This often happens with variables that
132 are local to a function.
135 1. The perl host is linked with perlX.lib to get perl_alloc. This
136 function will return a pointer to CPerlObj (the PERL_OBJECT). It
137 takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
138 for more information on this).
139 2. The perl host calls the same functions as normally would be
140 called in setting up and running a perl script, except that the
141 functions are now member functions of the PERL_OBJECT.
