35 /* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
37 Defining PERL_OBJECT turns on creation of a C++ object that
38 contains all writable core perl global variables and functions.
39 Stated another way, all necessary global variables and functions
40 are members of a big C++ object. This object's class is CPerlObj.
41 This allows a Perl Host to have multiple, independent perl
42 interpreters in the same process space. This is very important on
43 Win32 systems as the overhead of process creation is quite high --
44 this could be even higher than the script compile and execute time
47 The perl executable implementation on Win32 is composed of perl.exe
48 (the Perl Host) and perlX.dll. (the Perl Core). This allows the
49 same Perl Core to easily be embedded in other applications that use
58 +-----------+ +-----------+
59 | Perl Core |<->| Extension |
60 +-----------+ +-----------+ ...
62 Defining PERL_OBJECT has the following effects:
65 1. CPerlObj is defined (this is the PERL_OBJECT)
66 2. all static functions that needed to access either global
67 variables or functions needed are made member functions
68 3. all writable static variables are made member variables
69 4. all global variables and functions are defined as:
70 #define var CPerlObj::PL_var
71 #define func CPerlObj::Perl_func
72 * these are in embed.h
73 This necessitated renaming some local variables and functions that
74 had the same name as a global variable or function. This was
75 probably a _good_ thing anyway.
79 1. Access to global variables and perl functions is through a
80 pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
81 made transparent to extension developers by the following macros:
82 #define var pPerl->PL_var
83 #define func pPerl->Perl_func
84 * these are done in objXSUB.h
85 This requires that the extension be compiled as C++, which means
86 that the code must be ANSI C and not K&R C. For K&R extensions,
87 please see the C API notes located in Win32/GenCAPI.pl. This script
88 creates a perlCAPI.lib that provides a K & R compatible C interface
90 2. Local variables and functions cannot have the same name as perl's
91 variables or functions since the macros will redefine these. Look for
92 this if you get some strange error message and it does not look like
93 the code that you had written. This often happens with variables that
94 are local to a function.
97 1. The perl host is linked with perlX.lib to get perl_alloc. This
98 function will return a pointer to CPerlObj (the PERL_OBJECT). It
99 takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
100 for more information on this).
101 2. The perl host calls the same functions as normally would be
102 called in setting up and running a perl script, except that the
103 functions are now member functions of the PERL_OBJECT.

869 Specifically, perl internals don't support long long. Among
870 the many problems is that some compilers support long long,
871 but the underlying library functions (such as sprintf) don't.
872 Some things do work (such as quad pack/unpack on convex);
873 also some systems use long long for the fpos_t typedef. That
876 The IV type is supposed to be long enough to hold any integral
878 --Andy Dougherty August 1996
881 /* Much more 64-bit probing added. Now we should get Quad_t
882 in most systems: int64_t, long long, long, int, will do.
884 Beware of LP32 systems (ILP32, ILP32LL64). Such systems have been
885 used to sizeof(long) == sizeof(foo*). This is a bad assumption
886 because then IV/UV have been 32 bits, too. Which, in turn means
887 that even if the system has quads (e.g. long long), IV cannot be a
888 quad. Introducing a 64-bit IV (because of long long existing)
889 will introduce binary incompatibility.
891 Summary: a long long system needs to add -DUSE_LONG_LONG to $ccflags
892 to get quads -- and if its pointers are still 32 bits, this will break
893 binary compatibility. Casting an IV (a long long) to a pointer will
894 truncate half of the IV away.

1067 * and it must not be smaller than int because ~ does integral promotion.
1068 * <type>_MAX: (<type>) (U<type>_MAX >> 1)
1069 * <type>_MIN: -<type>_MAX - <is_twos_complement_architecture: (3 & -1) == 3>.
