passing a pointer to initialized structrue in a function

Show all headers | View raw

I have this structure like following :

typedef struct{
char static_data[10];
int a;
int b;
} my_ds;

i have initialized it like following:

my_ds * ds = (my_ds *)malloc(sizeof(my_ds));
memmove(my_ds->static_data, buf, len);
ds->a = c;
ds->b = d;

and passed it in a function:

int my_fun(void ** data);
my_fun((void *)&ds);

what happens inside my_fun, the first field, static[10] is initialized correctly but other two values are zero. What am i missing here?
