67/* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
68
69Defining PERL_OBJECT turns on creation of a C++ object that
70contains all writable core perl global variables and functions.
71Stated another way, all necessary global variables and functions
72are members of a big C++ object. This object's class is CPerlObj.
73This allows a Perl Host to have multiple, independent perl
74interpreters in the same process space. This is very important on
75Win32 systems as the overhead of process creation is quite high --
76this could be even higher than the script compile and execute time
77for small scripts.
78
79The perl executable implementation on Win32 is composed of perl.exe
80(the Perl Host) and perlX.dll. (the Perl Core). This allows the
81same Perl Core to easily be embedded in other applications that use
82the perl interpreter.
83

86+-----------+
87 ^

89 v
90+-----------+ +-----------+
91| Perl Core |<->| Extension |
92+-----------+ +-----------+ ...
93
94Defining PERL_OBJECT has the following effects:
95
96PERL CORE
971. CPerlObj is defined (this is the PERL_OBJECT)
982. all static functions that needed to access either global
99variables or functions needed are made member functions
1003. all writable static variables are made member variables
1014. all global variables and functions are defined as:
22c35a8c 102 #define var CPerlObj::PL_var
3dfd1da1 103 #define func CPerlObj::Perl_func
22c35a8c 104 * these are in embed.h
3dfd1da1
GS		 105This necessitated renaming some local variables and functions that
106had the same name as a global variable or function. This was
107probably a _good_ thing anyway.
108
109
110EXTENSIONS
1111. Access to global variables and perl functions is through a
112pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
113made transparent to extension developers by the following macros:
22c35a8c 114 #define var pPerl->PL_var
3dfd1da1 115 #define func pPerl->Perl_func
6de196ee 116 * these are done in objXSUB.h
3dfd1da1
GS		 117This requires that the extension be compiled as C++, which means
118that the code must be ANSI C and not K&R C. For K&R extensions,
119please see the C API notes located in Win32/GenCAPI.pl. This script
6de196ee 120creates a perlCAPI.lib that provides a K & R compatible C interface
3dfd1da1
GS		 121to the PERL_OBJECT.
1222. Local variables and functions cannot have the same name as perl's
123variables or functions since the macros will redefine these. Look for
124this if you get some strange error message and it does not look like
125the code that you had written. This often happens with variables that
126are local to a function.
127
128PERL HOST
1291. The perl host is linked with perlX.lib to get perl_alloc. This
130function will return a pointer to CPerlObj (the PERL_OBJECT). It
0f4eea8f
DL		 131takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
132for more information on this).
3dfd1da1
GS		 1332. The perl host calls the same functions as normally would be
134called in setting up and running a perl script, except that the
135functions are now member functions of the PERL_OBJECT.

907 Specifically, perl internals don't support long long. Among
908 the many problems is that some compilers support long long,
909 but the underlying library functions (such as sprintf) don't.
910 Some things do work (such as quad pack/unpack on convex);
911 also some systems use long long for the fpos_t typedef. That
912 seems to work too.
913
914 The IV type is supposed to be long enough to hold any integral
915 value or a pointer.

GS		 919/* Much more 64-bit probing added. Now we should get Quad_t
920 in most systems: int64_t, long long, long, int, will do.
921
922 Beware of LP32 systems (ILP32, ILP32LL64). Such systems have been
923 used to sizeof(long) == sizeof(foo*). This is a bad assumption
924 because then IV/UV have been 32 bits, too. Which, in turn means
925 that even if the system has quads (e.g. long long), IV cannot be a
926 quad. Introducing a 64-bit IV (because of long long existing)
85ab1d1d 927 will introduce binary incompatibility.
5ff3f7a4
GS		 928
929 Summary: a long long system needs to add -DUSE_LONG_LONG to $ccflags
930 to get quads -- and if its pointers are still 32 bits, this will break
931 binary compatibility. Casting an IV (a long long) to a pointer will
932 truncate half of the IV away.
