I am tempted to see if char* str[]; is a valid syntax or not

I think it's valid, but it does make things tricky ... and maybe it's that trickiness that inspired this thread in the first place.
It gets a lot easier if we're allowed to declare the struct as:
struct _Edje_Message_String_Set { int count; AV * str; };
Here's a demo using that very struct declaration.
# struct.pl # use strict; use warnings; use Inline C => Config => BUILD_NOISY => 1, CLEAN_AFTER_BUILD => 0, USING => 'ParseRegExp', ; use Inline C => <<'EOC'; struct _Edje_Message_String_Set { int count; AV * str; }; typedef struct _Edje_Message_String_Set EdjeMessageStringSet; void struct_size(void) { printf("Size of _Edje_Message_String_Set struct: %d\n", sizeof(EdjeMessageStringSet) ); } EdjeMessageStringSet * _new(AV * val_arr) { EdjeMessageStringSet *message; /* int i; */ /* SV ** elem; */ Newx(message, 1, EdjeMessageStringSet); if(message == NULL) croak("Failed to allocate memory in _new function"); message->count = av_len(val_arr) + 1; message->str = val_arr; return message; } void _iterate(EdjeMessageStringSet * strs) { int i; SV ** elem; for(i = 0; i < strs->count; i++) { elem = av_fetch(strs->str, i, 0); printf("%s\n", SvPV_nolen(*elem)); } } void DESTROY(EdjeMessageStringSet * x) { Safefree(x); printf("destroyed _new EdjeMessageStringSet*\n"); } void foo(AV * arref) { EdjeMessageStringSet *m; m = _new(arref); _iterate(m); DESTROY(m); } EOC struct_size(); my @in = ("hello foo", "hello bar","hello world", "goodbye"); # The XSub foo() will create a new EdjeMessageStringSet object # using _new(), then pass that object to _iterate() which # prints out all of the strings contained in the object. # Finally, foo() calls DESTROY() which frees the memory that # was assigned to create the EdjeMessageStringSet object. foo(\@in);
For me, that outputs:
Size of _Edje_Message_String_Set struct: 16 hello foo hello bar hello world goodbye destroyed _new EdjeMessageStringSet*
Cheers,
Rob

Title:

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
