26 /* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
28 Defining PERL_OBJECT turns on creation of a C++ object that
29 contains all writable core perl global variables and functions.
30 Stated another way, all necessary global variables and functions
31 are members of a big C++ object. This object's class is CPerlObj.
32 This allows a Perl Host to have multiple, independent perl
33 interpreters in the same process space. This is very important on
34 Win32 systems as the overhead of process creation is quite high --
35 this could be even higher than the script compile and execute time
38 The perl executable implementation on Win32 is composed of perl.exe
39 (the Perl Host) and perlX.dll. (the Perl Core). This allows the
40 same Perl Core to easily be embedded in other applications that use
49 +-----------+ +-----------+
50 | Perl Core |<->| Extension |
51 +-----------+ +-----------+ ...
53 Defining PERL_OBJECT has the following effects:
56 1. CPerlObj is defined (this is the PERL_OBJECT)
57 2. all static functions that needed to access either global
58 variables or functions needed are made member functions
59 3. all writable static variables are made member variables
60 4. all global variables and functions are defined as:
61 #define var CPerlObj::PL_var
62 #define func CPerlObj::Perl_func
63 * these are in embed.h
64 This necessitated renaming some local variables and functions that
65 had the same name as a global variable or function. This was
66 probably a _good_ thing anyway.
70 1. Access to global variables and perl functions is through a
71 pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
72 made transparent to extension developers by the following macros:
73 #define var pPerl->PL_var
74 #define func pPerl->Perl_func
75 * these are done in objXSUB.h
76 This requires that the extension be compiled as C++, which means
77 that the code must be ANSI C and not K&R C. For K&R extensions,
78 please see the C API notes located in Win32/GenCAPI.pl. This script
79 creates a perlCAPI.lib that provides a K & R compatible C interface
81 2. Local variables and functions cannot have the same name as perl's
82 variables or functions since the macros will redefine these. Look for
83 this if you get some strange error message and it does not look like
84 the code that you had written. This often happens with variables that
85 are local to a function.
88 1. The perl host is linked with perlX.lib to get perl_alloc. This
89 function will return a pointer to CPerlObj (the PERL_OBJECT). It
90 takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
91 for more information on this).
92 2. The perl host calls the same functions as normally would be
93 called in setting up and running a perl script, except that the
94 functions are now member functions of the PERL_OBJECT.

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

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