29 | /* PERL_OBJECT explained - DickH and DougL @ ActiveState.com |
30 | |
31 | Defining PERL_OBJECT turns on creation of a C++ object that |
32 | contains all writable core perl global variables and functions. |
33 | Stated another way, all necessary global variables and functions |
34 | are members of a big C++ object. This object's class is CPerlObj. |
35 | This allows a Perl Host to have multiple, independent perl |
36 | interpreters in the same process space. This is very important on |
37 | Win32 systems as the overhead of process creation is quite high -- |
38 | this could be even higher than the script compile and execute time |
39 | for small scripts. |
40 | |
41 | The perl executable implementation on Win32 is composed of perl.exe |
42 | (the Perl Host) and perlX.dll. (the Perl Core). This allows the |
43 | same Perl Core to easily be embedded in other applications that use |
44 | the perl interpreter. |

54 | +-----------+ +-----------+ ... |
55 | |
56 | Defining PERL_OBJECT has the following effects: |
57 | |
58 | PERL CORE |
59 | 1. CPerlObj is defined (this is the PERL_OBJECT) |
60 | 2. all static functions that needed to access either global |
61 | variables or functions needed are made member functions |
62 | 3. all writable static variables are made member variables |
63 | 4. all global variables and functions are defined as: |
64 | #define var CPerlObj::Perl_var |
65 | #define func CPerlObj::Perl_func |
66 | * these are in objpp.h |
67 | This necessitated renaming some local variables and functions that |
68 | had the same name as a global variable or function. This was |
69 | probably a _good_ thing anyway. |
70 | |
71 | |
72 | EXTENSIONS |
73 | 1. Access to global variables and perl functions is through a |
74 | pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is |
75 | made transparent to extension developers by the following macros: |
76 | #define var pPerl->Perl_var |
77 | #define func pPerl->Perl_func |
78 | * these are done in ObjXSub.h |
79 | This requires that the extension be compiled as C++, which means |
80 | that the code must be ANSI C and not K&R C. For K&R extensions, |
81 | please see the C API notes located in Win32/GenCAPI.pl. This script |
82 | creates a PerlCAPI.lib that provides a K & R compatible C interface |
83 | to the PERL_OBJECT. |
84 | 2. Local variables and functions cannot have the same name as perl's |
85 | variables or functions since the macros will redefine these. Look for |
86 | this if you get some strange error message and it does not look like |
87 | the code that you had written. This often happens with variables that |
88 | are local to a function. |
89 | |
90 | PERL HOST |
91 | 1. The perl host is linked with perlX.lib to get perl_alloc. This |
92 | function will return a pointer to CPerlObj (the PERL_OBJECT). It |
93 | takes pointers to the various PerlXXX_YYY interfaces (see ipdir.h for |
94 | information on this). |
95 | 2. The perl host calls the same functions as normally would be |
96 | called in setting up and running a perl script, except that the |
97 | functions are now member functions of the PERL_OBJECT. |

855 | /* |
856 | * Try to figure out max and min values for the integral types. THE CORRECT |
857 | * SOLUTION TO THIS MESS: ADAPT enquire.c FROM GCC INTO CONFIGURE. The |
858 | * following hacks are used if neither limits.h or values.h provide them: |
859 | * U<TYPE>_MAX: for types >= int: ~(unsigned TYPE)0 |
860 | * for types < int: (unsigned TYPE)~(unsigned)0 |
861 | * The argument to ~ must be unsigned so that later signed->unsigned |
862 | * conversion can't modify the value's bit pattern (e.g. -0 -> +0), |
863 | * and it must not be smaller than int because ~ does integral promotion. |
864 | * <type>_MAX: (<type>) (U<type>_MAX >> 1) |
865 | * <type>_MIN: -<type>_MAX - <is_twos_complement_architecture: (3 & -1) == 3>. |
866 | * The latter is a hack which happens to work on some machines but |
867 | * does *not* catch any random system, or things like integer types |
868 | * with NaN if that is possible. |
869 | * |
870 | * All of the types are explicitly cast to prevent accidental loss of |
871 | * numeric range, and in the hope that they will be less likely to confuse |
872 | * over-eager optimizers. |
