26/* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
27
28Defining PERL_OBJECT turns on creation of a C++ object that
29contains all writable core perl global variables and functions.
30Stated another way, all necessary global variables and functions
31are members of a big C++ object. This object's class is CPerlObj.
32This allows a Perl Host to have multiple, independent perl
33interpreters in the same process space. This is very important on
34Win32 systems as the overhead of process creation is quite high --
35this could be even higher than the script compile and execute time
36for small scripts.
37
38The perl executable implementation on Win32 is composed of perl.exe
39(the Perl Host) and perlX.dll. (the Perl Core). This allows the
40same Perl Core to easily be embedded in other applications that use
41the perl interpreter.

53Defining PERL_OBJECT has the following effects:
54
55PERL CORE
561. CPerlObj is defined (this is the PERL_OBJECT)
572. all static functions that needed to access either global
58variables or functions needed are made member functions
593. all writable static variables are made member variables
604. 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 64This necessitated renaming some local variables and functions that
65had the same name as a global variable or function. This was
66probably a _good_ thing anyway.
67
68
69EXTENSIONS
701. Access to global variables and perl functions is through a
71pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
72made 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 76This requires that the extension be compiled as C++, which means
77that the code must be ANSI C and not K&R C. For K&R extensions,
78please see the C API notes located in Win32/GenCAPI.pl. This script
6de196ee 79creates a perlCAPI.lib that provides a K & R compatible C interface
3dfd1da1 80to the PERL_OBJECT.
812. Local variables and functions cannot have the same name as perl's
82variables or functions since the macros will redefine these. Look for
83this if you get some strange error message and it does not look like
84the code that you had written. This often happens with variables that
85are local to a function.
86
87PERL HOST
881. The perl host is linked with perlX.lib to get perl_alloc. This
89function will return a pointer to CPerlObj (the PERL_OBJECT). It
0f4eea8f 90takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
91for more information on this).
3dfd1da1 922. The perl host calls the same functions as normally would be
93called in setting up and running a perl script, except that the
94functions 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.
821 --Andy Dougherty August 1996
822*/
823
5ff3f7a4 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.
