Accessing Struct variables from JNI using SWIG

[Bharath Raghunathan]

Hello,

I have a library with the following structure:


typedef struct val_variable_string {
int offset;
int size;
char first_byte;
} val_t;

There is a function that operates on the above structure as shown below


int fun1(val_t *v)
{

int i;
char *ptr= &v->first_byte;

for (i=0; i< v->size; i++)
printf ("%c", ptr);

printf ("\n");
}

Since this is a c variable structure it is allocated in the following
way and passed onto the above function as below:

mv1 = (struct val_variable_string *) malloc(sizeof(struct
val_variable_string) + 20 );

mv1->offset = 0 ;

mv1->size = strlen(TEST_STRING);

strncpy ( &mv1->first_byte, TEST_STRING, mv1->size);


fun1(mv1);


Now Can the JNI code be generated to achieve a similar functionality
using SWIG? Is there any alternate way to achieve the above
functionality from JAVA layer.

Any help is appreciated.

Thanks in Advance
