68/* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
69
70Defining PERL_OBJECT turns on creation of a C++ object that
71contains all writable core perl global variables and functions.
72Stated another way, all necessary global variables and functions
73are members of a big C++ object. This object's class is CPerlObj.
74This allows a Perl Host to have multiple, independent perl
75interpreters in the same process space. This is very important on
76Win32 systems as the overhead of process creation is quite high --
77this could be even higher than the script compile and execute time
78for small scripts.
79
80The perl executable implementation on Win32 is composed of perl.exe
81(the Perl Host) and perlX.dll. (the Perl Core). This allows the
82same Perl Core to easily be embedded in other applications that use
83the perl interpreter.
84

87+-----------+
88 ^

91+-----------+ +-----------+
92| Perl Core |<->| Extension |
93+-----------+ +-----------+ ...
94
95Defining PERL_OBJECT has the following effects:
96
97PERL CORE
981. CPerlObj is defined (this is the PERL_OBJECT)
992. all static functions that needed to access either global
100variables or functions needed are made member functions
1013. all writable static variables are made member variables
1024. all global variables and functions are defined as:
22c35a8c 103 #define var CPerlObj::PL_var
3dfd1da1 104 #define func CPerlObj::Perl_func
22c35a8c 105 * these are in embed.h
3dfd1da1
GS		 106This necessitated renaming some local variables and functions that
107had the same name as a global variable or function. This was
108probably a _good_ thing anyway.
109
110
111EXTENSIONS
1121. Access to global variables and perl functions is through a
113pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
114made transparent to extension developers by the following macros:
22c35a8c 115 #define var pPerl->PL_var
3dfd1da1 116 #define func pPerl->Perl_func
6de196ee 117 * these are done in objXSUB.h
3dfd1da1
GS		 118This requires that the extension be compiled as C++, which means
119that the code must be ANSI C and not K&R C. For K&R extensions,
120please see the C API notes located in Win32/GenCAPI.pl. This script
6de196ee 121creates a perlCAPI.lib that provides a K & R compatible C interface
3dfd1da1
GS		 122to the PERL_OBJECT.
1232. Local variables and functions cannot have the same name as perl's
124variables or functions since the macros will redefine these. Look for
125this if you get some strange error message and it does not look like
126the code that you had written. This often happens with variables that
127are local to a function.
128
129PERL HOST
1301. The perl host is linked with perlX.lib to get perl_alloc. This
131function will return a pointer to CPerlObj (the PERL_OBJECT). It
0f4eea8f
DL		 132takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
133for more information on this).
3dfd1da1
GS		 1342. The perl host calls the same functions as normally would be
135called in setting up and running a perl script, except that the
136functions are now member functions of the PERL_OBJECT.

899 Specifically, perl internals don't support long long. Among
900 the many problems is that some compilers support long long,
901 but the underlying library functions (such as sprintf) don't.
902 Some things do work (such as quad pack/unpack on convex);
903 also some systems use long long for the fpos_t typedef. That
904 seems to work too.
905
906 The IV type is supposed to be long enough to hold any integral
907 value or a pointer.

GS		 911/* Much more 64-bit probing added. Now we should get Quad_t
912 in most systems: int64_t, long long, long, int, will do.
913
914 Beware of LP32 systems (ILP32, ILP32LL64). Such systems have been
915 used to sizeof(long) == sizeof(foo*). This is a bad assumption
916 because then IV/UV have been 32 bits, too. Which, in turn means
917 that even if the system has quads (e.g. long long), IV cannot be a
918 quad. Introducing a 64-bit IV (because of long long existing)
85ab1d1d 919 will introduce binary incompatibility.
5ff3f7a4
GS		 920
921 Summary: a long long system needs to add -DUSE_LONG_LONG to $ccflags
922 to get quads -- and if its pointers are still 32 bits, this will break
923 binary compatibility. Casting an IV (a long long) to a pointer will
924 truncate half of the IV away.
