Thread: Whats wrong with this code?

Code:

int importFile(const char* filename, double content[], int len)
{
    FILE* fp = fopen(filename, "r");
    double input;
    int i;


    if(fp == NULL)
    {
        printf("ERROR");
        fclose(fp);
        return -1;
    }


    for(i = 0; i < len; i++)
    {
        fgets(content, len, fpin);
        if (sscanf(content, "%lf", &input) == 1)
        {
            content[i] = input;


        }
    }


    fclose(fp);
    return 0;
}
