68 | /* PERL_OBJECT explained - DickH and DougL @ ActiveState.com | |
69 | ||
70 | Defining PERL_OBJECT turns on creation of a C++ object that | |
71 | contains all writable core perl global variables and functions. | |
72 | Stated another way, all necessary global variables and functions | |
73 | are members of a big C++ object. This object's class is CPerlObj. | |
74 | This allows a Perl Host to have multiple, independent perl | |
75 | interpreters in the same process space. This is very important on | |
76 | Win32 systems as the overhead of process creation is quite high -- | |
77 | this could be even higher than the script compile and execute time | |
78 | for small scripts. | |
79 | ||
80 | The perl executable implementation on Win32 is composed of perl.exe | |
81 | (the Perl Host) and perlX.dll. (the Perl Core). This allows the | |
82 | same Perl Core to easily be embedded in other applications that use | |
83 | the perl interpreter. | |
84 | ||

92 | | Perl Core |<->| Extension | | |
93 | +-----------+ +-----------+ ... | |
94 | ||
95 | Defining PERL_OBJECT has the following effects: | |
96 | ||
97 | PERL CORE | |
98 | 1. CPerlObj is defined (this is the PERL_OBJECT) | |
99 | 2. all static functions that needed to access either global | |
100 | variables or functions needed are made member functions | |
101 | 3. all writable static variables are made member variables | |
102 | 4. all global variables and functions are defined as: | |
22c35a8c | 103 | #define var CPerlObj::PL_var |
3dfd1da1 | 104 | #define func CPerlObj::Perl_func |
22c35a8c | 105 | * these are in embed.h |
3dfd1da1 GS |
106 | This necessitated renaming some local variables and functions that |
107 | had the same name as a global variable or function. This was | |
108 | probably a _good_ thing anyway. | |
109 | ||
110 | ||
111 | EXTENSIONS | |
112 | 1. Access to global variables and perl functions is through a | |
113 | pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is | |
114 | made transparent to extension developers by the following macros: | |
22c35a8c | 115 | #define var pPerl->PL_var |
3dfd1da1 | 116 | #define func pPerl->Perl_func |
6de196ee | 117 | * these are done in objXSUB.h |
3dfd1da1 GS |
118 | This requires that the extension be compiled as C++, which means |
119 | that the code must be ANSI C and not K&R C. For K&R extensions, | |
120 | please see the C API notes located in Win32/GenCAPI.pl. This script | |
6de196ee | 121 | creates a perlCAPI.lib that provides a K & R compatible C interface |
3dfd1da1 GS |
122 | to the PERL_OBJECT. |
123 | 2. Local variables and functions cannot have the same name as perl's | |
124 | variables or functions since the macros will redefine these. Look for | |
125 | this if you get some strange error message and it does not look like | |
126 | the code that you had written. This often happens with variables that | |
127 | are local to a function. | |
128 | ||
129 | PERL HOST | |
130 | 1. The perl host is linked with perlX.lib to get perl_alloc. This | |
131 | function will return a pointer to CPerlObj (the PERL_OBJECT). It | |
0f4eea8f DL |
132 | takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h |
133 | for more information on this). | |
3dfd1da1 GS |
134 | 2. The perl host calls the same functions as normally would be |
135 | called in setting up and running a perl script, except that the | |
136 | functions are now member functions of the PERL_OBJECT. | |

899 | Specifically, perl internals don't support long long. Among | |
900 | the many problems is that some compilers support long long, | |
901 | but the underlying library functions (such as sprintf) don't. | |
902 | Some things do work (such as quad pack/unpack on convex); | |
903 | also some systems use long long for the fpos_t typedef. That | |
904 | seems to work too. | |
905 | ||
906 | The IV type is supposed to be long enough to hold any integral | |
907 | value or a pointer. | |

911 | /* Much more 64-bit probing added. Now we should get Quad_t |
912 | in most systems: int64_t, long long, long, int, will do. | |
913 | ||
914 | Beware of LP32 systems (ILP32, ILP32LL64). Such systems have been | |
915 | used to sizeof(long) == sizeof(foo*). This is a bad assumption | |
916 | because then IV/UV have been 32 bits, too. Which, in turn means | |
917 | that even if the system has quads (e.g. long long), IV cannot be a | |
918 | quad. Introducing a 64-bit IV (because of long long existing) | |
85ab1d1d | 919 | will introduce binary incompatibility. |
5ff3f7a4 GS |
920 | |
921 | Summary: a long long system needs to add -DUSE_LONG_LONG to $ccflags | |
922 | to get quads -- and if its pointers are still 32 bits, this will break | |
923 | binary compatibility. Casting an IV (a long long) to a pointer will | |
924 | truncate half of the IV away. | |
