68 /* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
70 Defining PERL_OBJECT turns on creation of a C++ object that
71 contains all writable core perl global variables and functions.
72 Stated another way, all necessary global variables and functions
73 are members of a big C++ object. This object's class is CPerlObj.
74 This allows a Perl Host to have multiple, independent perl
75 interpreters in the same process space. This is very important on
76 Win32 systems as the overhead of process creation is quite high --
77 this could be even higher than the script compile and execute time
80 The perl executable implementation on Win32 is composed of perl.exe
81 (the Perl Host) and perlX.dll. (the Perl Core). This allows the
82 same Perl Core to easily be embedded in other applications that use
91 +-----------+ +-----------+
92 | Perl Core |<->| Extension |
93 +-----------+ +-----------+ ...
95 Defining PERL_OBJECT has the following effects:
98 1. CPerlObj is defined (this is the PERL_OBJECT)
99 2. all static functions that needed to access either global
100 variables or functions needed are made member functions
101 3. all writable static variables are made member variables
102 4. all global variables and functions are defined as:
103 #define var CPerlObj::PL_var
104 #define func CPerlObj::Perl_func
105 * these are in embed.h
106 This necessitated renaming some local variables and functions that
107 had the same name as a global variable or function. This was
108 probably a _good_ thing anyway.
112 1. Access to global variables and perl functions is through a
113 pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
114 made transparent to extension developers by the following macros:
115 #define var pPerl->PL_var
116 #define func pPerl->Perl_func
117 * these are done in objXSUB.h
118 This requires that the extension be compiled as C++, which means
119 that the code must be ANSI C and not K&R C. For K&R extensions,
120 please see the C API notes located in Win32/GenCAPI.pl. This script
121 creates a perlCAPI.lib that provides a K & R compatible C interface
123 2. Local variables and functions cannot have the same name as perl's
124 variables or functions since the macros will redefine these. Look for
125 this if you get some strange error message and it does not look like
126 the code that you had written. This often happens with variables that
127 are local to a function.
130 1. The perl host is linked with perlX.lib to get perl_alloc. This
131 function will return a pointer to CPerlObj (the PERL_OBJECT). It
132 takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
133 for more information on this).
134 2. The perl host calls the same functions as normally would be
135 called in setting up and running a perl script, except that the
136 functions are now member functions of the PERL_OBJECT.

895 The IV type is supposed to be long enough to hold any integral
897 --Andy Dougherty August 1996
900 /* We should be able to get Quad_t in most systems:
901 all of int64_t, long long, long, int, will work.
903 Beware of LP32 systems (ILP32, ILP32LL64). Such systems have been
904 used to sizeof(long) == sizeof(foo*). This is a bad assumption
905 because then IV/UV have been 32 bits, too. Which, in turn means
906 that even if the system has quads (e.g. long long), IV cannot be a
907 quad. Introducing a 64-bit IV (because of long long existing)
908 will introduce binary incompatibility.
910 Summary: a long long system needs to add -DUSE_LONG_LONG to $ccflags
911 to get quads -- and if its pointers are still 32 bits, this will break
912 binary compatibility. Casting an IV (a long long) to a pointer will
913 truncate half of the IV away. Most systems can just use
914 Configure -Duse64bits to get the -DUSE_LONG_LONG added either by
915 their hints files, or directly by Configure if they are using gcc.
