29/* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
30
31Defining PERL_OBJECT turns on creation of a C++ object that
32contains all writable core perl global variables and functions.
33Stated another way, all necessary global variables and functions
34are members of a big C++ object. This object's class is CPerlObj.
35This allows a Perl Host to have multiple, independent perl
36interpreters in the same process space. This is very important on
37Win32 systems as the overhead of process creation is quite high --
38this could be even higher than the script compile and execute time
39for small scripts.
40
41The perl executable implementation on Win32 is composed of perl.exe
42(the Perl Host) and perlX.dll. (the Perl Core). This allows the
43same Perl Core to easily be embedded in other applications that use
44the perl interpreter.

55
56Defining PERL_OBJECT has the following effects:
57
58PERL CORE
591. CPerlObj is defined (this is the PERL_OBJECT)
602. all static functions that needed to access either global
61variables or functions needed are made member functions
623. all writable static variables are made member variables
634. all global variables and functions are defined as:
64 #define var CPerlObj::Perl_var
65 #define func CPerlObj::Perl_func
66 * these are in objpp.h
67This necessitated renaming some local variables and functions that
68had the same name as a global variable or function. This was
69probably a _good_ thing anyway.
70
71
72EXTENSIONS
731. Access to global variables and perl functions is through a
74pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
75made transparent to extension developers by the following macros:
76 #define var pPerl->Perl_var
77 #define func pPerl->Perl_func
6de196ee 78 * these are done in objXSUB.h
3dfd1da1
GS		 79This requires that the extension be compiled as C++, which means
80that the code must be ANSI C and not K&R C. For K&R extensions,
81please see the C API notes located in Win32/GenCAPI.pl. This script
6de196ee 82creates a perlCAPI.lib that provides a K & R compatible C interface
3dfd1da1
GS		 83to the PERL_OBJECT.
842. Local variables and functions cannot have the same name as perl's
85variables or functions since the macros will redefine these. Look for
86this if you get some strange error message and it does not look like
87the code that you had written. This often happens with variables that
88are local to a function.
89
90PERL HOST
911. The perl host is linked with perlX.lib to get perl_alloc. This
92function will return a pointer to CPerlObj (the PERL_OBJECT). It
0f4eea8f
DL		 93takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
94for more information on this).
3dfd1da1
GS		 952. The perl host calls the same functions as normally would be
96called in setting up and running a perl script, except that the
97functions are now member functions of the PERL_OBJECT.

817 Specifically, perl internals don't support long long. Among
818 the many problems is that some compilers support long long,
819 but the underlying library functions (such as sprintf) don't.
820 Some things do work (such as quad pack/unpack on convex);
821 also some systems use long long for the fpos_t typedef. That
822 seems to work too.
823
824 The IV type is supposed to be long enough to hold any integral
825 value or a pointer.

GS		 829/* Much more 64-bit probing added. Now we should get Quad_t
830 in most systems: int64_t, long long, long, int, will do.
831
832 Beware of LP32 systems (ILP32, ILP32LL64). Such systems have been
833 used to sizeof(long) == sizeof(foo*). This is a bad assumption
834 because then IV/UV have been 32 bits, too. Which, in turn means
835 that even if the system has quads (e.g. long long), IV cannot be a
836 quad. Introducing a 64-bit IV (because of long long existing)
85ab1d1d 837 will introduce binary incompatibility.
5ff3f7a4
GS		 838
839 Summary: a long long system needs to add -DUSE_LONG_LONG to $ccflags
840 to get quads -- and if its pointers are still 32 bits, this will break
841 binary compatibility. Casting an IV (a long long) to a pointer will
842 truncate half of the IV away.
