Array reallocation in C:

 

{

     somestruct *s;

 

     s = malloc( sizeof(somestruct) * num_of_elements );

 

     /* use s like you would any array */

     s[index].field = 0;

 

     /* later, make the s array bigger, but keep the existing values.

        note that the realloc'd size is the total of old size + desired

        new elements */

     s = realloc(s, (sizeof(somestruct) * new_num_of_elements));

}
