72 /* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
74 Defining PERL_OBJECT turns on creation of a C++ object that
75 contains all writable core perl global variables and functions.
76 Stated another way, all necessary global variables and functions
77 are members of a big C++ object. This object's class is CPerlObj.
78 This allows a Perl Host to have multiple, independent perl
79 interpreters in the same process space. This is very important on
80 Win32 systems as the overhead of process creation is quite high --
81 this could be even higher than the script compile and execute time
84 The perl executable implementation on Win32 is composed of perl.exe
85 (the Perl Host) and perlX.dll. (the Perl Core). This allows the
86 same Perl Core to easily be embedded in other applications that use
95 +-----------+ +-----------+
96 | Perl Core |<->| Extension |
97 +-----------+ +-----------+ ...
99 Defining PERL_OBJECT has the following effects:
102 1. CPerlObj is defined (this is the PERL_OBJECT)
103 2. all static functions that needed to access either global
104 variables or functions needed are made member functions
105 3. all writable static variables are made member variables
106 4. all global variables and functions are defined as:
107 #define var CPerlObj::PL_var
108 #define func CPerlObj::Perl_func
109 * these are in embed.h
110 This necessitated renaming some local variables and functions that
111 had the same name as a global variable or function. This was
112 probably a _good_ thing anyway.
116 1. Access to global variables and perl functions is through a
117 pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
118 made transparent to extension developers by the following macros:
119 #define var pPerl->PL_var
120 #define func pPerl->Perl_func
121 * these are done in objXSUB.h
122 This requires that the extension be compiled as C++, which means
123 that the code must be ANSI C and not K&R C. For K&R extensions,
124 please see the C API notes located in Win32/GenCAPI.pl. This script
125 creates a perlCAPI.lib that provides a K & R compatible C interface
127 2. Local variables and functions cannot have the same name as perl's
128 variables or functions since the macros will redefine these. Look for
129 this if you get some strange error message and it does not look like
130 the code that you had written. This often happens with variables that
131 are local to a function.
134 1. The perl host is linked with perlX.lib to get perl_alloc. This
135 function will return a pointer to CPerlObj (the PERL_OBJECT). It
136 takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
137 for more information on this).
138 2. The perl host calls the same functions as normally would be
139 called in setting up and running a perl script, except that the
140 functions are now member functions of the PERL_OBJECT.
