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

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

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