Dynamic array of structs and function call f(const struct_type *const data[])

Question

The following code warns about incompatible type. What is the proper way to solve this code?

thanks

typedef struct a_struct struct_type;

void f(cons         


        

Answer 1

f expects to get as input an array of pointers (const struct_type* []). You pass a pointer to a pointer of struct (const struct_type**).

The best thing to do, IMO, is to change the signature of f to:

void f(const struct_type *const* data);

Why do you need to pass arrays as arguments to functions?
