Hello, I have to bind a C library with struct inside. I read the most common help (struct netconfig Netconfig;....) But it doesn't work...damned , each time a do the make of my module i have a "Bad pointer type in paramater number 1" . the header is like it 
typedef struct { unsigned *char test;} s_test;
extern void my_function(s_test * my_struct);

      yes excuse me , i forgot the most important... the xs file is like this (exactly) : 
      #include "EXTERN.h"
#include "perl.h"
#include "XSUB.h"
#include "ppport.h"
#include "test.h"

typedef struct s_test Test;

MODULE = Tests    PACKAGE = Tests

void
my_function(ptr_struct)
Test * ptr_struct

      and in thetypemap file i added the following line : 
      Test *  T_PTROBJ

        Note that your s_test is a type: 
        typedef struct { unsigned *char test;} s_test;

        not a struct (which is anonymous here). So you'd probably better: 
        
typedef s_test Test; /* Removed "struct" */

        and see if this fixes your problem.

        Flavio (perl -e 'print(scalar(reverse("\nti.xittelop\@oivalf")))')

        Don't fool yourself.
