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 |
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 |
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 |
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 |
90 | takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h |
91 | for more information on this). |
3dfd1da1 |
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. |

812 | Specifically, perl internals don't support long long. Among |
813 | the many problems is that some compilers support long long, |
814 | but the underlying library functions (such as sprintf) don't. |
815 | Some things do work (such as quad pack/unpack on convex); |
816 | also some systems use long long for the fpos_t typedef. That |
817 | seems to work too. |
818 | |
819 | The IV type is supposed to be long enough to hold any integral |
820 | value or a pointer. |

824 | /* Much more 64-bit probing added. Now we should get Quad_t |
825 | in most systems: int64_t, long long, long, int, will do. |
826 | |
827 | Beware of LP32 systems (ILP32, ILP32LL64). Such systems have been |
828 | used to sizeof(long) == sizeof(foo*). This is a bad assumption |
829 | because then IV/UV have been 32 bits, too. Which, in turn means |
830 | that even if the system has quads (e.g. long long), IV cannot be a |
831 | quad. Introducing a 64-bit IV (because of long long existing) |
85ab1d1d |
832 | will introduce binary incompatibility. |
5ff3f7a4 |
833 | |
834 | Summary: a long long system needs to add -DUSE_LONG_LONG to $ccflags |
835 | to get quads -- and if its pointers are still 32 bits, this will break |
836 | binary compatibility. Casting an IV (a long long) to a pointer will |
837 | truncate half of the IV away. |
