You could also do like the following:
typedef struct idata {
sometype data1;
sometype2 data2;
struct idata *next;
} idata;
You can then create a string of idata structs and access the next one. You
will have to create a function that will allocate a new one under
idata->next when needed, a function to search them and a function to free
the string. When creating a new one always make idata->next = NULL so that
you can use it to determine if you have reached the end of the string.
This is what is done in WAPUniverse.
