Question

struct aPoint {
        int somaVertical;
        int somaHorizontal;
        int valor;
};

I have an array of structs dynamically created in main(), like so:

struct aPoint *ps = malloc( sizeof(struct aPoint) * columns * rows )

And I want to work with its struct values outside of main() in a function that has sscanf(). The initialization of the array is also taken care of on the main().

How can I pass the array of structs through that function and set some struct values of it aswell? Argh I hate pointering!

Thanks!

Answer 1

That would be:

    int readStuff(struct aPoint *ps, size_t len, const char *someVar)
    {
        unsigned int i;
        for (i = 0; i < len; i++) {
           sscanf(someVar, "%d", &(ps[i].somaVertical));
           /* And so on for the other fields */
        }
        /* Return whatever you're returning here */
    }

    const size_t len = colunas * linhas;
    struct aPoint *ps = calloc(len, sizeof(struct aPoint));
    int success = readStuff(ps, len, arrayOfNumbers);
