hi,

i managed to get my struct to work.the problem i am having now is i am trying to use calloc memory allocation but i keep getting a segmentation fault and i don't know how to fix it. i don't think i am declaring the calloc properly and storing the result of encode properly.

here is my code that i am using.

#include <stdio.h>
#include <stdlib.h>
typedef struct code1
{
    unsigned short key[2];

    unsigned short text[2];
}code;


    void encode(short* v, short* k)

    { ... }


    void decode(short* v,short* k)

    { ... }


    main(int argc, char *argv[])

    {

        unsigned short key1[2],key2[2];

        unsigned short p[2],c[2];


        struct code1 *test, *entry;

        entry = (unsigned short *) calloc(2, sizeof (code));

        key1[0]=0x0000;

        key1[1]=0x0000;

        short i;

        p[0]=0x0001;

        p[1]=0x0002;


        for (i=0; key1[0] < 0x0002; i++)
        {
            for (i=0; key1[1] < 0x000A; i++)

            {

                encode(p, key1);

                test[i].key[0] = key1[0];
                test[i].key[1] = key1[1];
                test[i].text[0] = p[0];
                test[i].text[1] = p[1];

            }

        }

} //end main

can anybody help?

thanks,

sc
