86/* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
87
88Defining PERL_OBJECT turns on creation of a C++ object that
89contains all writable core perl global variables and functions.
90Stated another way, all necessary global variables and functions
91are members of a big C++ object. This object's class is CPerlObj.
92This allows a Perl Host to have multiple, independent perl
93interpreters in the same process space. This is very important on
94Win32 systems as the overhead of process creation is quite high --
95this could be even higher than the script compile and execute time
96for small scripts.
97
98The perl executable implementation on Win32 is composed of perl.exe
99(the Perl Host) and perlX.dll. (the Perl Core). This allows the
100same Perl Core to easily be embedded in other applications that use
101the perl interpreter.

111+-----------+ +-----------+ ...
112
113Defining PERL_OBJECT has the following effects:
114
115PERL CORE
1161. CPerlObj is defined (this is the PERL_OBJECT)
1172. all static functions that needed to access either global
118variables or functions needed are made member functions
1193. all writable static variables are made member variables
1204. all global variables and functions are defined as:
22c35a8c 121 #define var CPerlObj::PL_var
3dfd1da1 122 #define func CPerlObj::Perl_func
22c35a8c 123 * these are in embed.h
3dfd1da1
GS		 124This necessitated renaming some local variables and functions that
125had the same name as a global variable or function. This was
126probably a _good_ thing anyway.
127
128
129EXTENSIONS
1301. Access to global variables and perl functions is through a
131pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
132made transparent to extension developers by the following macros:
22c35a8c 133 #define var pPerl->PL_var
3dfd1da1 134 #define func pPerl->Perl_func
6de196ee 135 * these are done in objXSUB.h
3dfd1da1
GS		 136This requires that the extension be compiled as C++, which means
137that the code must be ANSI C and not K&R C. For K&R extensions,
138please see the C API notes located in Win32/GenCAPI.pl. This script
6de196ee 139creates a perlCAPI.lib that provides a K & R compatible C interface
3dfd1da1
GS		 140to the PERL_OBJECT.
1412. Local variables and functions cannot have the same name as perl's
142variables or functions since the macros will redefine these. Look for
143this if you get some strange error message and it does not look like
144the code that you had written. This often happens with variables that
145are local to a function.
146
147PERL HOST
1481. The perl host is linked with perlX.lib to get perl_alloc. This
149function will return a pointer to CPerlObj (the PERL_OBJECT). It
0f4eea8f
DL		 150takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
151for more information on this).
3dfd1da1
GS		 1522. The perl host calls the same functions as normally would be
153called in setting up and running a perl script, except that the
154functions are now member functions of the PERL_OBJECT.

1111 I've tracked down a weird bug in Perl5.6.1 to the UTS compiler's
1112 mishandling of MY_UV_MAX in util.c. It is defined as

1114 # define MY_UV_MAX ((UV)IV_MAX * (UV)2 + (UV)1)
1115 #endif
1116 The compiler handles {double floating point value} >= MY_UV_MAX as if
1117 MY_UV_MAX were the signed integer -1. In fact it will do the same
1118 thing with (UV)(0xffffffff), in place of MY_UV_MAX, though 0xffffffff
1119 *without* the typecast to UV works fine.
