26 | /* PERL_OBJECT explained - DickH and DougL @ ActiveState.com | |
27 | ||
28 | Defining PERL_OBJECT turns on creation of a C++ object that | |
29 | contains all writable core perl global variables and functions. | |
30 | Stated another way, all necessary global variables and functions | |
31 | are members of a big C++ object. This object's class is CPerlObj. | |
32 | This allows a Perl Host to have multiple, independent perl | |
33 | interpreters in the same process space. This is very important on | |
34 | Win32 systems as the overhead of process creation is quite high -- | |
35 | this could be even higher than the script compile and execute time | |
36 | for small scripts. | |
37 | ||
38 | The perl executable implementation on Win32 is composed of perl.exe | |
39 | (the Perl Host) and perlX.dll. (the Perl Core). This allows the | |
40 | same Perl Core to easily be embedded in other applications that use | |
41 | the perl interpreter. | |

51 | +-----------+ +-----------+ ... | |
52 | ||
53 | Defining PERL_OBJECT has the following effects: | |
54 | ||
55 | PERL CORE | |
56 | 1. CPerlObj is defined (this is the PERL_OBJECT) | |
57 | 2. all static functions that needed to access either global | |
58 | variables or functions needed are made member functions | |
59 | 3. all writable static variables are made member variables | |
60 | 4. all global variables and functions are defined as: | |
22c35a8c | 61 | #define var CPerlObj::PL_var |
3dfd1da1 | 62 | #define func CPerlObj::Perl_func |
22c35a8c | 63 | * these are in embed.h |
3dfd1da1 GS |
64 | This necessitated renaming some local variables and functions that |
65 | had the same name as a global variable or function. This was | |
66 | probably a _good_ thing anyway. | |
67 | ||
68 | ||
69 | EXTENSIONS | |
70 | 1. Access to global variables and perl functions is through a | |
71 | pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is | |
72 | made transparent to extension developers by the following macros: | |
22c35a8c | 73 | #define var pPerl->PL_var |
3dfd1da1 | 74 | #define func pPerl->Perl_func |
6de196ee | 75 | * these are done in objXSUB.h |
3dfd1da1 GS |
76 | This requires that the extension be compiled as C++, which means |
77 | that the code must be ANSI C and not K&R C. For K&R extensions, | |
78 | please see the C API notes located in Win32/GenCAPI.pl. This script | |
6de196ee | 79 | creates a perlCAPI.lib that provides a K & R compatible C interface |
3dfd1da1 GS |
80 | to the PERL_OBJECT. |
81 | 2. Local variables and functions cannot have the same name as perl's | |
82 | variables or functions since the macros will redefine these. Look for | |
83 | this if you get some strange error message and it does not look like | |
84 | the code that you had written. This often happens with variables that | |
85 | are local to a function. | |
86 | ||
87 | PERL HOST | |
88 | 1. The perl host is linked with perlX.lib to get perl_alloc. This | |
89 | function will return a pointer to CPerlObj (the PERL_OBJECT). It | |
0f4eea8f DL |
90 | takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h |
91 | for more information on this). | |
3dfd1da1 GS |
92 | 2. The perl host calls the same functions as normally would be |
93 | called in setting up and running a perl script, except that the | |
94 | functions are now member functions of the PERL_OBJECT. | |

797 | Some things do work (such as quad pack/unpack on convex); | |
798 | also some systems use long long for the fpos_t typedef. That | |
799 | seems to work too. | |

806 | /* Much more 64-bit probing added. Now we should get Quad_t |
807 | in most systems: int64_t, long long, long, int, will do. | |
808 | ||
809 | Beware of LP32 systems (ILP32, ILP32LL64). Such systems have been | |
810 | used to sizeof(long) == sizeof(foo*). This is a bad assumption | |
811 | because then IV/UV have been 32 bits, too. Which, in turn means | |
812 | that even if the system has quads (e.g. long long), IV cannot be a | |
813 | quad. Introducing a 64-bit IV (because of long long existing) | |
85ab1d1d | 814 | will introduce binary incompatibility. |
5ff3f7a4 GS |
815 | |
816 | Summary: a long long system needs to add -DUSE_LONG_LONG to $ccflags | |
817 | to get quads -- and if its pointers are still 32 bits, this will break | |
818 | binary compatibility. Casting an IV (a long long) to a pointer will | |
819 | truncate half of the IV away. | |
