67 /* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
69 Defining PERL_OBJECT turns on creation of a C++ object that
70 contains all writable core perl global variables and functions.
71 Stated another way, all necessary global variables and functions
72 are members of a big C++ object. This object's class is CPerlObj.
73 This allows a Perl Host to have multiple, independent perl
74 interpreters in the same process space. This is very important on
75 Win32 systems as the overhead of process creation is quite high --
76 this could be even higher than the script compile and execute time
79 The perl executable implementation on Win32 is composed of perl.exe
80 (the Perl Host) and perlX.dll. (the Perl Core). This allows the
81 same Perl Core to easily be embedded in other applications that use
90 +-----------+ +-----------+
91 | Perl Core |<->| Extension |
92 +-----------+ +-----------+ ...
94 Defining PERL_OBJECT has the following effects:
97 1. CPerlObj is defined (this is the PERL_OBJECT)
98 2. all static functions that needed to access either global
99 variables or functions needed are made member functions
100 3. all writable static variables are made member variables
101 4. all global variables and functions are defined as:
102 #define var CPerlObj::PL_var
103 #define func CPerlObj::Perl_func
104 * these are in embed.h
105 This necessitated renaming some local variables and functions that
106 had the same name as a global variable or function. This was
107 probably a _good_ thing anyway.
111 1. Access to global variables and perl functions is through a
112 pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
113 made transparent to extension developers by the following macros:
114 #define var pPerl->PL_var
115 #define func pPerl->Perl_func
116 * these are done in objXSUB.h
117 This requires that the extension be compiled as C++, which means
118 that the code must be ANSI C and not K&R C. For K&R extensions,
119 please see the C API notes located in Win32/GenCAPI.pl. This script
120 creates a perlCAPI.lib that provides a K & R compatible C interface
122 2. Local variables and functions cannot have the same name as perl's
123 variables or functions since the macros will redefine these. Look for
124 this if you get some strange error message and it does not look like
125 the code that you had written. This often happens with variables that
126 are local to a function.
129 1. The perl host is linked with perlX.lib to get perl_alloc. This
130 function will return a pointer to CPerlObj (the PERL_OBJECT). It
131 takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
132 for more information on this).
133 2. The perl host calls the same functions as normally would be
134 called in setting up and running a perl script, except that the
135 functions are now member functions of the PERL_OBJECT.

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

1103 * U<TYPE>_MAX: for types >= int: ~(unsigned TYPE)0

1105 * The argument to ~ must be unsigned so that later signed->unsigned
1106 * conversion can't modify the value's bit pattern (e.g. -0 -> +0),
1107 * and it must not be smaller than int because ~ does integral promotion.
1108 * <type>_MAX: (<type>) (U<type>_MAX >> 1)
1109 * <type>_MIN: -<type>_MAX - <is_twos_complement_architecture: (3 & -1) == 3>.

1111 * does *not* catch any random system, or things like integer types
1112 * with NaN if that is possible.
1114 * All of the types are explicitly cast to prevent accidental loss of
