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

52Defining PERL_OBJECT has the following effects:
53
54PERL CORE
551. CPerlObj is defined (this is the PERL_OBJECT)
562. all static functions that needed to access either global
57variables or functions needed are made member functions
583. all writable static variables are made member variables
594. all global variables and functions are defined as:
22c35a8c 60 #define var CPerlObj::PL_var
3dfd1da1 61 #define func CPerlObj::Perl_func
22c35a8c 62 * these are in embed.h
3dfd1da1
GS		 63This necessitated renaming some local variables and functions that
64had the same name as a global variable or function. This was
65probably a _good_ thing anyway.
66
67
68EXTENSIONS
691. Access to global variables and perl functions is through a
70pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
71made transparent to extension developers by the following macros:
22c35a8c 72 #define var pPerl->PL_var
3dfd1da1 73 #define func pPerl->Perl_func
6de196ee 74 * these are done in objXSUB.h
3dfd1da1
GS		 75This requires that the extension be compiled as C++, which means
76that the code must be ANSI C and not K&R C. For K&R extensions,
77please see the C API notes located in Win32/GenCAPI.pl. This script
6de196ee 78creates a perlCAPI.lib that provides a K & R compatible C interface
3dfd1da1
GS		 79to the PERL_OBJECT.
802. Local variables and functions cannot have the same name as perl's
81variables or functions since the macros will redefine these. Look for
82this if you get some strange error message and it does not look like
83the code that you had written. This often happens with variables that
84are local to a function.
85
86PERL HOST
871. The perl host is linked with perlX.lib to get perl_alloc. This
88function will return a pointer to CPerlObj (the PERL_OBJECT). It
0f4eea8f
DL		 89takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
90for more information on this).
3dfd1da1
GS		 912. The perl host calls the same functions as normally would be
92called in setting up and running a perl script, except that the
93functions are now member functions of the PERL_OBJECT.

794 Specifically, perl internals don't support long long. Among
795 the many problems is that some compilers support long long,
796 but the underlying library functions (such as sprintf) don't.
797 Some things do work (such as quad pack/unpack on convex);
798 also some systems use long long for the fpos_t typedef. That
799 seems to work too.

801 The IV type is supposed to be long enough to hold any integral
802 value or a pointer.

807 in most systems: int64_t, long long, long, int, will do.
808
809 Beware of LP32 systems (ILP32, ILP32LL64). Such systems have been
810 used to sizeof(long) == sizeof(foo*). This is a bad assumption
811 because then IV/UV have been 32 bits, too. Which, in turn means
812 that even if the system has quads (e.g. long long), IV cannot be a
813 quad. Introducing a 64-bit IV (because of long long existing)
85ab1d1d 814 will introduce binary incompatibility.
5ff3f7a4
GS		 815
816 Summary: a long long system needs to add -DUSE_LONG_LONG to $ccflags
817 to get quads -- and if its pointers are still 32 bits, this will break
818 binary compatibility. Casting an IV (a long long) to a pointer will
819 truncate half of the IV away.
