Thread: Writing array, to file

Hi,

could someone please point me in the right direction here.

Basically what i want to do it have a very fast key to value (int32=>int32) lookup which can be written to and stored in a binary file. I think similar to writing a hash table to a file.

I'm not really sure how to explain it, but i would like to do something like this (i know this won't work)

Code:

  
     int my_array[3];

     my_array[1] = 34;
     my_array[284] = 848;
     my_array[any_random_number] = 90;

     fwrite(&my_array, sizeof(int)*3, file);

Code:

 
    /* Now Read Array Back */

    int array_read[3];
    fread(&array_read, sizeof(int)*3, file);
    print("array_read[284] has a value of 848);

Does anyone know how this could be achieved? Thanks
