70 /* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
72 Defining PERL_OBJECT turns on creation of a C++ object that
73 contains all writable core perl global variables and functions.
74 Stated another way, all necessary global variables and functions
75 are members of a big C++ object. This object's class is CPerlObj.
76 This allows a Perl Host to have multiple, independent perl
77 interpreters in the same process space. This is very important on
78 Win32 systems as the overhead of process creation is quite high --
79 this could be even higher than the script compile and execute time
82 The perl executable implementation on Win32 is composed of perl.exe
83 (the Perl Host) and perlX.dll. (the Perl Core). This allows the
84 same Perl Core to easily be embedded in other applications that use
93 +-----------+ +-----------+
94 | Perl Core |<->| Extension |
95 +-----------+ +-----------+ ...
97 Defining PERL_OBJECT has the following effects:
100 1. CPerlObj is defined (this is the PERL_OBJECT)
101 2. all static functions that needed to access either global
102 variables or functions needed are made member functions
103 3. all writable static variables are made member variables
104 4. all global variables and functions are defined as:
105 #define var CPerlObj::PL_var
106 #define func CPerlObj::Perl_func
107 * these are in embed.h
108 This necessitated renaming some local variables and functions that
109 had the same name as a global variable or function. This was
110 probably a _good_ thing anyway.
114 1. Access to global variables and perl functions is through a
115 pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
116 made transparent to extension developers by the following macros:
117 #define var pPerl->PL_var
118 #define func pPerl->Perl_func
119 * these are done in objXSUB.h
120 This requires that the extension be compiled as C++, which means
121 that the code must be ANSI C and not K&R C. For K&R extensions,
122 please see the C API notes located in Win32/GenCAPI.pl. This script
123 creates a perlCAPI.lib that provides a K & R compatible C interface
125 2. Local variables and functions cannot have the same name as perl's
126 variables or functions since the macros will redefine these. Look for
127 this if you get some strange error message and it does not look like
128 the code that you had written. This often happens with variables that
129 are local to a function.
132 1. The perl host is linked with perlX.lib to get perl_alloc. This
133 function will return a pointer to CPerlObj (the PERL_OBJECT). It
134 takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
135 for more information on this).
136 2. The perl host calls the same functions as normally would be
137 called in setting up and running a perl script, except that the
138 functions are now member functions of the PERL_OBJECT.

911 /* XXX QUAD stuff is not currently supported on most systems.
912 Specifically, perl internals don't support long long. Among
913 the many problems is that some compilers support long long,
914 but the underlying library functions (such as sprintf) don't.
915 Some things do work (such as quad pack/unpack on convex);
916 also some systems use long long for the fpos_t typedef. That
919 The IV type is supposed to be long enough to hold any integral
921 --Andy Dougherty August 1996
924 /* Much more 64-bit probing added. Now we should get Quad_t
925 in most systems: int64_t, long long, long, int, will do.
927 Beware of LP32 systems (ILP32, ILP32LL64). Such systems have been
928 used to sizeof(long) == sizeof(foo*). This is a bad assumption
929 because then IV/UV have been 32 bits, too. Which, in turn means
930 that even if the system has quads (e.g. long long), IV cannot be a
931 quad. Introducing a 64-bit IV (because of long long existing)
932 will introduce binary incompatibility.
934 Summary: a long long system needs to add -DUSE_LONG_LONG to $ccflags
935 to get quads -- and if its pointers are still 32 bits, this will break
936 binary compatibility. Casting an IV (a long long) to a pointer will
937 truncate half of the IV away.

1125 * U<TYPE>_MAX: for types >= int: ~(unsigned TYPE)0
1126 * for types < int: (unsigned TYPE)~(unsigned)0

1128 * conversion can't modify the value's bit pattern (e.g. -0 -> +0),
1129 * and it must not be smaller than int because ~ does integral promotion.
1130 * <type>_MAX: (<type>) (U<type>_MAX >> 1)
1131 * <type>_MIN: -<type>_MAX - <is_twos_complement_architecture: (3 & -1) == 3>.

1133 * does *not* catch any random system, or things like integer types
1134 * with NaN if that is possible.
1136 * All of the types are explicitly cast to prevent accidental loss of
