82 | /* PERL_OBJECT explained - DickH and DougL @ ActiveState.com |
83 | |
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 |
92 | for small scripts. |
93 | |
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 |
97 | the perl interpreter. |
98 | |

106 | | Perl Core |<->| Extension | |
107 | +-----------+ +-----------+ ... |
108 | |
109 | Defining PERL_OBJECT has the following effects: |
110 | |
111 | PERL CORE |
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: |
22c35a8c |
117 | #define var CPerlObj::PL_var |
3dfd1da1 |
118 | #define func CPerlObj::Perl_func |
22c35a8c |
119 | * these are in embed.h |
3dfd1da1 |
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. |
123 | |
124 | |
125 | EXTENSIONS |
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: |
22c35a8c |
129 | #define var pPerl->PL_var |
3dfd1da1 |
130 | #define func pPerl->Perl_func |
6de196ee |
131 | * these are done in objXSUB.h |
3dfd1da1 |
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 |
6de196ee |
135 | creates a perlCAPI.lib that provides a K & R compatible C interface |
3dfd1da1 |
136 | to the PERL_OBJECT. |
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. |
142 | |
143 | PERL HOST |
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 |
0f4eea8f |
146 | takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h |
147 | for more information on this). |
3dfd1da1 |
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. |
