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

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

802 | Specifically, perl internals don't support long long. Among |
803 | the many problems is that some compilers support long long, |
804 | but the underlying library functions (such as sprintf) don't. |
805 | Some things do work (such as quad pack/unpack on convex); |
806 | also some systems use long long for the fpos_t typedef. That |
807 | seems to work too. |
808 | |
809 | The IV type is supposed to be long enough to hold any integral |
810 | value or a pointer. |
811 | --Andy Dougherty August 1996 |

5ff3f7a4 |
814 | /* Much more 64-bit probing added. Now we should get Quad_t |
815 | in most systems: int64_t, long long, long, int, will do. |
816 | |
817 | Beware of LP32 systems (ILP32, ILP32LL64). Such systems have been |
818 | used to sizeof(long) == sizeof(foo*). This is a bad assumption |
819 | because then IV/UV have been 32 bits, too. Which, in turn means |
820 | that even if the system has quads (e.g. long long), IV cannot be a |
821 | quad. Introducing a 64-bit IV (because of long long existing) |
85ab1d1d |
822 | will introduce binary incompatibility. |
5ff3f7a4 |
823 | |
824 | Summary: a long long system needs to add -DUSE_LONG_LONG to $ccflags |
825 | to get quads -- and if its pointers are still 32 bits, this will break |
826 | binary compatibility. Casting an IV (a long long) to a pointer will |
827 | truncate half of the IV away. |
