62 | /* PERL_OBJECT explained - DickH and DougL @ ActiveState.com | |
63 | ||
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 | |
72 | for small scripts. | |
73 | ||
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 | |
77 | the perl interpreter. | |

86 | | Perl Core |<->| Extension | | |
87 | +-----------+ +-----------+ ... | |
88 | ||
89 | Defining PERL_OBJECT has the following effects: | |
90 | ||
91 | PERL CORE | |
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: | |
22c35a8c | 97 | #define var CPerlObj::PL_var |
3dfd1da1 | 98 | #define func CPerlObj::Perl_func |
22c35a8c | 99 | * these are in embed.h |
3dfd1da1 GS |
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. | |
103 | ||
104 | ||
105 | EXTENSIONS | |
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: | |
22c35a8c | 109 | #define var pPerl->PL_var |
3dfd1da1 | 110 | #define func pPerl->Perl_func |
6de196ee | 111 | * these are done in objXSUB.h |
3dfd1da1 GS |
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 | |
6de196ee | 115 | creates a perlCAPI.lib that provides a K & R compatible C interface |
3dfd1da1 GS |
116 | to the PERL_OBJECT. |
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. | |
122 | ||
123 | PERL HOST | |
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 | |
0f4eea8f DL |
126 | takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h |
127 | for more information on this). | |
3dfd1da1 GS |
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. | |
