29 /* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
31 Defining PERL_OBJECT turns on creation of a C++ object that
32 contains all writable core perl global variables and functions.
33 Stated another way, all necessary global variables and functions
34 are members of a big C++ object. This object's class is CPerlObj.
35 This allows a Perl Host to have multiple, independent perl
36 interpreters in the same process space. This is very important on
37 Win32 systems as the overhead of process creation is quite high --
38 this could be even higher than the script compile and execute time
41 The perl executable implementation on Win32 is composed of perl.exe
42 (the Perl Host) and perlX.dll. (the Perl Core). This allows the
43 same Perl Core to easily be embedded in other applications that use
52 +-----------+ +-----------+
53 | Perl Core |<->| Extension |
54 +-----------+ +-----------+ ...
56 Defining PERL_OBJECT has the following effects:
59 1. CPerlObj is defined (this is the PERL_OBJECT)
60 2. all static functions that needed to access either global
61 variables or functions needed are made member functions
62 3. all writable static variables are made member variables
63 4. 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
67 This necessitated renaming some local variables and functions that
68 had the same name as a global variable or function. This was
69 probably a _good_ thing anyway.
73 1. Access to global variables and perl functions is through a
74 pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
75 made transparent to extension developers by the following macros:
76 #define var pPerl->Perl_var
77 #define func pPerl->Perl_func
78 * these are done in objXSUB.h
79 This requires that the extension be compiled as C++, which means
80 that the code must be ANSI C and not K&R C. For K&R extensions,
81 please see the C API notes located in Win32/GenCAPI.pl. This script
82 creates a perlCAPI.lib that provides a K & R compatible C interface
84 2. Local variables and functions cannot have the same name as perl's
85 variables or functions since the macros will redefine these. Look for
86 this if you get some strange error message and it does not look like
87 the code that you had written. This often happens with variables that
88 are local to a function.
91 1. The perl host is linked with perlX.lib to get perl_alloc. This
92 function will return a pointer to CPerlObj (the PERL_OBJECT). It
93 takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
94 for more information on this).
95 2. The perl host calls the same functions as normally would be
96 called in setting up and running a perl script, except that the
97 functions are now member functions of the PERL_OBJECT.

819 Specifically, perl internals don't support long long. Among
820 the many problems is that some compilers support long long,
821 but the underlying library functions (such as sprintf) don't.
822 Some things do work (such as quad pack/unpack on convex);
823 also some systems use long long for the fpos_t typedef. That
826 The IV type is supposed to be long enough to hold any integral
828 --Andy Dougherty August 1996
831 /* Much more 64-bit probing added. Now we should get Quad_t
832 in most systems: int64_t, long long, long, int, will do.
834 Beware of LP32 systems (ILP32, ILP32LL64). Such systems have been
835 used to sizeof(long) == sizeof(foo*). This is a bad assumption
836 because then IV/UV have been 32 bits, too. Which, in turn means
837 that even if the system has quads (e.g. long long), IV cannot be a
838 quad. Introducing a 64-bit IV (because of long long existing)
839 would introduce binary incompatibility. Therefore the
840 USE_LONG_LONG guard below when probing for quads and the check for
841 PTRSIZE further down when defining IV/UV.
843 Summary: a long long system needs to add -DUSE_LONG_LONG to $ccflags
844 to get quads -- and if its pointers are still 32 bits, this will break
845 binary compatibility. Casting an IV (a long long) to a pointer will
846 truncate half of the IV away.

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