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