passing data structures to function pointers and get there values

[heepoo]

hi all,
please see this example and say what should i do

typedef struct example_dt_struct {
int a;
float b;
char* c;
};
typedef void(*func)(example_dt_struct *s, int e, int f);
void f(func *n)
{

}

how can i use example_dt_structure with my function pointer into f()
thanks in advance

void f(func *n)
{
    example_dt_struct foo;
    n(&foo, 0, 0);
}

ok, how can i access foo.a or foo.b or foo.c?

[MiiNiPaa]

through the passed pointer

void some_function(example_dt_struct *s, int e, int f)
{
    s -> a = e;
}

void f(func *n)
{
    example_dt_struct foo;
    n(&foo, 0, 0);
}

int main()
{
    f(some_function);
}

ok, how can i access a variable in a function type?
for example, from a function, get access to a parameter of a typedef?

In my example func is a typedef.
