above the main in my program, right befor the function prototypes.

can anybody tell me if this is correct?
I also dont know how to send either a single entry struct or an entire
index array to a function(by address, I must alter them).
can someone tell me what the prototype, function header and actual
function call should look like??
if you so desire to see the entire program it is at:

Any help would be greatly appreciated

Before you buy.

typedef struct {
                            char word[25];
                            int page;
                            int length;

struct entry {
                            char word[25];
                            int page;
                            int length;

As you can obviously see the former is more comprehensive.

And in order to send the structure to a function as an argument, you'll have
to send the address to the function and store it in a pointer.
i.e.
index idx1;
function(&idx1);

and the function would be like:

function(index *idx) {
                            for (int i=0;i<100li++) {
                                printf("Word: %s",idx[i]->word);
//idx[i]->word  OR   (*idx[i]).word
                                printf("Page: %d",idx[i]->page);
//           -DO-
                                printf("Length: %d",idx[i]->length);
//            -DO-

index idx1,*idx;
idx=&idx1;
function(idx);

and the function would be like:

function(index *idx) {
                            for (int i=0;i<100li++) {
                                printf("Word: %s",idx[i]->word);
//idx[i]->word  OR   (*idx[i]).word
                                printf("Page: %d",idx[i]->page);
//           -DO-
                                printf("Length: %d",idx[i]->length);
//            -DO-

typedef struct {
                            char word[25];
                            int page;
                            int length;

struct entry {
                            char word[25];

Though Al's answer was correct, in general typedefing an
array is not something you would want to do in a real
program (because it is too confusing for the reader). Also
in a real program you would probably want to #define
MAX_ENTRIES 100 if you wanted to be able to change the
array size flexibly.

function add entry should be prototyped.:
void add_entry(index p, size_t *n);
And in function definition of add_entry change the "->" operators to "."
operators.
And in function main, the call to: add_entry(dict, &count);

There is another problem which has occurred when I compiled with gcc.
There is a conflict of symbol 'index' with code in string.h.
Is 'index' reserved?
