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