35/* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
36
37Defining PERL_OBJECT turns on creation of a C++ object that
38contains all writable core perl global variables and functions.
39Stated another way, all necessary global variables and functions
40are members of a big C++ object. This object's class is CPerlObj.
41This allows a Perl Host to have multiple, independent perl
42interpreters in the same process space. This is very important on
43Win32 systems as the overhead of process creation is quite high --
44this could be even higher than the script compile and execute time
45for small scripts.
46
47The perl executable implementation on Win32 is composed of perl.exe
48(the Perl Host) and perlX.dll. (the Perl Core). This allows the
49same Perl Core to easily be embedded in other applications that use
50the perl interpreter.

60+-----------+ +-----------+ ...
61
62Defining PERL_OBJECT has the following effects:
63
64PERL CORE
651. CPerlObj is defined (this is the PERL_OBJECT)
662. all static functions that needed to access either global
67variables or functions needed are made member functions
683. all writable static variables are made member variables
694. all global variables and functions are defined as:
22c35a8c 70 #define var CPerlObj::PL_var
3dfd1da1 71 #define func CPerlObj::Perl_func
22c35a8c 72 * these are in embed.h
3dfd1da1
GS		 73This necessitated renaming some local variables and functions that
74had the same name as a global variable or function. This was
75probably a _good_ thing anyway.
76
77
78EXTENSIONS
791. Access to global variables and perl functions is through a
80pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
81made transparent to extension developers by the following macros:
22c35a8c 82 #define var pPerl->PL_var
3dfd1da1 83 #define func pPerl->Perl_func
6de196ee 84 * these are done in objXSUB.h
3dfd1da1
GS		 85This requires that the extension be compiled as C++, which means
86that the code must be ANSI C and not K&R C. For K&R extensions,
87please see the C API notes located in Win32/GenCAPI.pl. This script
6de196ee 88creates a perlCAPI.lib that provides a K & R compatible C interface
3dfd1da1
GS		 89to the PERL_OBJECT.
902. Local variables and functions cannot have the same name as perl's
91variables or functions since the macros will redefine these. Look for
92this if you get some strange error message and it does not look like
93the code that you had written. This often happens with variables that
94are local to a function.
95
96PERL HOST
971. The perl host is linked with perlX.lib to get perl_alloc. This
98function will return a pointer to CPerlObj (the PERL_OBJECT). It
0f4eea8f
DL		 99takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
100for more information on this).
3dfd1da1
GS		 1012. The perl host calls the same functions as normally would be
102called in setting up and running a perl script, except that the
103functions are now member functions of the PERL_OBJECT.

866 Specifically, perl internals don't support long long. Among
867 the many problems is that some compilers support long long,
868 but the underlying library functions (such as sprintf) don't.
869 Some things do work (such as quad pack/unpack on convex);
870 also some systems use long long for the fpos_t typedef. That
871 seems to work too.
872
873 The IV type is supposed to be long enough to hold any integral
874 value or a pointer.

GS		 878/* Much more 64-bit probing added. Now we should get Quad_t
879 in most systems: int64_t, long long, long, int, will do.
880
881 Beware of LP32 systems (ILP32, ILP32LL64). Such systems have been
882 used to sizeof(long) == sizeof(foo*). This is a bad assumption
883 because then IV/UV have been 32 bits, too. Which, in turn means
884 that even if the system has quads (e.g. long long), IV cannot be a
885 quad. Introducing a 64-bit IV (because of long long existing)
85ab1d1d 886 will introduce binary incompatibility.
5ff3f7a4
GS		 887
888 Summary: a long long system needs to add -DUSE_LONG_LONG to $ccflags
889 to get quads -- and if its pointers are still 32 bits, this will break
890 binary compatibility. Casting an IV (a long long) to a pointer will
891 truncate half of the IV away.
