How to implement stringlist ???

Hi experts,

I want to implement a common stringlist.
My stringlist.h with my structire looks like:

typedef struct _stringlist {
        char    **strings;
        size_t    count;
} StringList;

Now i want to implement the following function:

StringList* stringlist_insert(StringList* list,
                              char* name)

My initializing function looks like:

StringList* stringlist_initialize()
{
    StringList *stringlist = malloc(sizeof(StringList));
    if (stringlist == NULL)
        return NULL;
   
        stringlist->count = 0;
        stringlist->strings = malloc(stringlist->sl_max*
                                     sizeof(char *));
        if (stringlist->strings == NULL)
            return NULL;
       
        return stringlist;
}


I have little problems with pointers, so can
anybody please help me , how to implement the
insert function ???????????????????????????????
