Working with self-made dynamic array

[Powdertrail]

Hello! I am trying to create a dynamic vector (as is in here; it's from an assignment - it has to respect this format. Bear in mind that names in here are not reserved words as this is translated from spanish).

There's a routine/function that's called vector_obtain, and must save in "value" the value from vector's position "pos". I am not told what data type does vector contain. vector_get_size does what it says on the tin.
Although it compiles, it doesn't work. This routine runs after "vector_save_on", a function that saves certain values on the vector I've to work with. What am I doing wrong?

bool vector_obtain (vector_t* vector, size_t pos, int* value)
{
    if ((pos>=0)&&(pos<vector_get_size(vector)))
    {
        value=(vector[pos].data);
        return true;
    }
    else return false;

bool vector_save_on(vector_t* vector, size_t pos, int value)
{
    if ((pos>=0)&&(pos<vector_get_size(vector)))
    {
        vector[sizeof(vector->data)*pos].data=value;
        return true;
    }
    else
       return false;
}


}

On the .h file, vector is defined as:

typedef struct vector {
    size_t size;
    int* data;
} vector_t;

value=(vector[pos].data);

perhaps it should read: *value=vector->data[pos];

vector[sizeof(vector->data)*pos].data=value;

should read: vector->data[pos] = value;
it's because the indexing operator (i.e. subscript operator) automatically takes account of the site of the data being pointed to.

Thank you very much! That did it!
