25 /* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
27 Defining PERL_OBJECT turns on creation of a C++ object that
28 contains all writable core perl global variables and functions.
29 Stated another way, all necessary global variables and functions
30 are members of a big C++ object. This object's class is CPerlObj.
31 This allows a Perl Host to have multiple, independent perl
32 interpreters in the same process space. This is very important on
33 Win32 systems as the overhead of process creation is quite high --
34 this could be even higher than the script compile and execute time
37 The perl executable implementation on Win32 is composed of perl.exe
38 (the Perl Host) and perlX.dll. (the Perl Core). This allows the
39 same Perl Core to easily be embedded in other applications that use
48 +-----------+ +-----------+
49 | Perl Core |<->| Extension |
50 +-----------+ +-----------+ ...
52 Defining PERL_OBJECT has the following effects:
55 1. CPerlObj is defined (this is the PERL_OBJECT)
56 2. all static functions that needed to access either global
57 variables or functions needed are made member functions
58 3. all writable static variables are made member variables
59 4. all global variables and functions are defined as:
60 #define var CPerlObj::PL_var
61 #define func CPerlObj::Perl_func
62 * these are in embed.h
63 This necessitated renaming some local variables and functions that
64 had the same name as a global variable or function. This was
65 probably a _good_ thing anyway.
69 1. Access to global variables and perl functions is through a
70 pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
71 made transparent to extension developers by the following macros:
72 #define var pPerl->PL_var
73 #define func pPerl->Perl_func
74 * these are done in objXSUB.h
75 This requires that the extension be compiled as C++, which means
76 that the code must be ANSI C and not K&R C. For K&R extensions,
77 please see the C API notes located in Win32/GenCAPI.pl. This script
78 creates a perlCAPI.lib that provides a K & R compatible C interface
80 2. Local variables and functions cannot have the same name as perl's
81 variables or functions since the macros will redefine these. Look for
82 this if you get some strange error message and it does not look like
83 the code that you had written. This often happens with variables that
84 are local to a function.
87 1. The perl host is linked with perlX.lib to get perl_alloc. This
88 function will return a pointer to CPerlObj (the PERL_OBJECT). It
89 takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
90 for more information on this).
91 2. The perl host calls the same functions as normally would be
92 called in setting up and running a perl script, except that the
93 functions are now member functions of the PERL_OBJECT.

802 Specifically, perl internals don't support long long. Among
803 the many problems is that some compilers support long long,
804 but the underlying library functions (such as sprintf) don't.
805 Some things do work (such as quad pack/unpack on convex);
806 also some systems use long long for the fpos_t typedef. That
809 The IV type is supposed to be long enough to hold any integral
811 --Andy Dougherty August 1996
814 /* Much more 64-bit probing added. Now we should get Quad_t
815 in most systems: int64_t, long long, long, int, will do.
817 Beware of LP32 systems (ILP32, ILP32LL64). Such systems have been
818 used to sizeof(long) == sizeof(foo*). This is a bad assumption
819 because then IV/UV have been 32 bits, too. Which, in turn means
820 that even if the system has quads (e.g. long long), IV cannot be a
821 quad. Introducing a 64-bit IV (because of long long existing)
822 will introduce binary incompatibility.
824 Summary: a long long system needs to add -DUSE_LONG_LONG to $ccflags
825 to get quads -- and if its pointers are still 32 bits, this will break
826 binary compatibility. Casting an IV (a long long) to a pointer will
827 truncate half of the IV away.

956 * Try to figure out max and min values for the integral types. THE CORRECT
957 * SOLUTION TO THIS MESS: ADAPT enquire.c FROM GCC INTO CONFIGURE. The
958 * following hacks are used if neither limits.h or values.h provide them:
959 * U<TYPE>_MAX: for types >= int: ~(unsigned TYPE)0
960 * for types < int: (unsigned TYPE)~(unsigned)0
961 * The argument to ~ must be unsigned so that later signed->unsigned
962 * conversion can't modify the value's bit pattern (e.g. -0 -> +0),
963 * and it must not be smaller than int because ~ does integral promotion.
964 * <type>_MAX: (<type>) (U<type>_MAX >> 1)
965 * <type>_MIN: -<type>_MAX - <is_twos_complement_architecture: (3 & -1) == 3>.
966 * The latter is a hack which happens to work on some machines but
967 * does *not* catch any random system, or things like integer types
968 * with NaN if that is possible.
970 * All of the types are explicitly cast to prevent accidental loss of
971 * numeric range, and in the hope that they will be less likely to confuse
972 * over-eager optimizers.
