This object's class is CPerlObj. -This allows a Perl Host to have multiple, independent perl -interpreters in the same process space. This is very important on -Win32 systems as the overhead of process creation is quite high -- -this could be even higher than the script compile and execute time -for small scripts. - -The perl executable implementation on Win32 is composed of perl.exe -(the Perl Host) and perlX.dll. (the Perl Core). This allows the -same Perl Core to easily be embedded in other applications that use -the perl interpreter. - -+-----------+ -| Perl Host | -+-----------+ - ^ - | - v -+-----------+ +-----------+ -| Perl Core |<->| Extension | -+-----------+ +-----------+ ... - -Defining PERL_OBJECT has the following effects: - -PERL CORE -1. CPerlObj is defined (this is the PERL_OBJECT) -2. all static functions that needed to access either global -variables or functions needed are made member functions -3. all writable static variables are made member variables -4. all global variables and functions are defined as: - #define var CPerlObj::PL_var - #define func CPerlObj::Perl_func - * these are in embed.h -This necessitated renaming some local variables and functions that -had the same name as a global variable or function. This was -probably a _good_ thing anyway. - - -EXTENSIONS -1. Access to global variables and perl functions is through a -pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is -made transparent to extension developers by the following macros: - #define var pPerl->PL_var - #define func pPerl->Perl_func - * these are done in objXSUB.h -This requires that the extension be compiled as C++, which means -that the code must be ANSI C and not K&R C. For K&R extensions, -please see the C API notes located in Win32/GenCAPI.pl. This script -creates a perlCAPI.lib that provides a K & R compatible C interface -to the PERL_OBJECT. -2. Local variables and functions cannot have the same name as perl's -variables or functions since the macros will redefine these. Look for -this if you get some strange error message and it does not look like -the code that you had written. This often happens with variables that -are local to a function. - -PERL HOST -1. The perl host is linked with perlX.lib to get perl_alloc. This -function will return a pointer to CPerlObj (the PERL_OBJECT). It -takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h -for more information on this). -2. The perl host calls the same functions as normally would be -called in setting up and running a perl script, except that the -functions are now member functions of the PERL_OBJECT. - -*/ - - -class CPerlObj; - -#define STATIC -#define CPERLscope(x) CPerlObj::x -#define CALL_FPTR(fptr) (aTHXo->*fptr) - -#define pTHXo CPerlObj *pPerl -#define pTHXo_ pTHXo, -#define aTHXo this -#define aTHXo_ this, -#define PERL_OBJECT_THIS aTHXo -#define PERL_OBJECT_THIS_ aTHXo_ -#define dTHXoa(a) pTHXo = (CPerlObj*)a -#define dTHXo pTHXo = PERL_GET_THX - -#define pTHXx void -#define pTHXx_ -#define aTHXx -#define aTHXx_ - -#else /* !PERL_OBJECT */ +/* <--- here ends the logic shared by perl.h and makedef.pl */ #ifdef PERL_IMPLICIT_CONTEXT -# ifdef USE_THREADS +# ifdef USE_5005THREADS struct perl_thread; -# define pTHX register struct perl_thread *thr +# define pTHX register struct perl_thread *thr PERL_UNUSED_DECL #
