70/* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
71
72Defining PERL_OBJECT turns on creation of a C++ object that
73contains all writable core perl global variables and functions.
74Stated another way, all necessary global variables and functions
75are members of a big C++ object. This object's class is CPerlObj.
76This allows a Perl Host to have multiple, independent perl
77interpreters in the same process space. This is very important on
78Win32 systems as the overhead of process creation is quite high --
79this could be even higher than the script compile and execute time
80for small scripts.
81
82The perl executable implementation on Win32 is composed of perl.exe
83(the Perl Host) and perlX.dll. (the Perl Core). This allows the
84same Perl Core to easily be embedded in other applications that use
85the perl interpreter.
86

95+-----------+ +-----------+ ...
96
97Defining PERL_OBJECT has the following effects:
98
99PERL CORE
1001. CPerlObj is defined (this is the PERL_OBJECT)
1012. all static functions that needed to access either global
102variables or functions needed are made member functions
1033. all writable static variables are made member variables
1044. all global variables and functions are defined as:
22c35a8c 105 #define var CPerlObj::PL_var
3dfd1da1 106 #define func CPerlObj::Perl_func
22c35a8c 107 * these are in embed.h
3dfd1da1 108This necessitated renaming some local variables and functions that
109had the same name as a global variable or function. This was
110probably a _good_ thing anyway.
111
112
113EXTENSIONS
1141. Access to global variables and perl functions is through a
115pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
116made transparent to extension developers by the following macros:
22c35a8c 117 #define var pPerl->PL_var
3dfd1da1 118 #define func pPerl->Perl_func
6de196ee 119 * these are done in objXSUB.h
3dfd1da1 120This requires that the extension be compiled as C++, which means
121that the code must be ANSI C and not K&R C. For K&R extensions,
122please see the C API notes located in Win32/GenCAPI.pl. This script
6de196ee 123creates a perlCAPI.lib that provides a K & R compatible C interface
3dfd1da1 124to the PERL_OBJECT.
1252. Local variables and functions cannot have the same name as perl's
126variables or functions since the macros will redefine these. Look for
127this if you get some strange error message and it does not look like
128the code that you had written. This often happens with variables that
129are local to a function.
130
131PERL HOST
1321. The perl host is linked with perlX.lib to get perl_alloc. This
133function will return a pointer to CPerlObj (the PERL_OBJECT). It
0f4eea8f 134takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
135for more information on this).
3dfd1da1 1362. The perl host calls the same functions as normally would be
137called in setting up and running a perl script, except that the
138functions are now member functions of the PERL_OBJECT.

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
917 seems to work too.
918
919 The IV type is supposed to be long enough to hold any integral
920 value or a pointer.
921 --Andy Dougherty August 1996
922*/
923
5ff3f7a4 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.
926
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)
85ab1d1d 932 will introduce binary incompatibility.
5ff3f7a4 933
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.
