Read Write fopen
Text fgetc fprintf "r", "w"
fgets fputc "rb", "wb"

binary fread

size_t fread(void *p, size_t size, size_tn, FILE * f);
size_t fwrite(

int count = fread(&w, sizeof(int), 1, f);
count += fread(&h,...,1,f)

if(count ==2)
{

void fclose(FILE *f)

int feof(FILE *f)

dynamic structures?

struct Blokus
{
int clirn,
char* data;

}

typedef struct IntValue {
int value;
struct IntValue *next;
} IntValue;

IntValue *IntValue_create(int value)
{
IntValue *iv = malloc(sizeof(IntValue));
iv->value = value;
iv->next = NULL;
return iv;
}

void IntValue_destroy(IntValue *iv)
{
free(iv);
}

IntValue *IntValueL_insertFront(IntValue *head, IntValue *node)
{
node->next = head;
return node;
}

void IntValueL_print(IntValue *head)
{
whle (head!= NULL) {
printf(" %d", head->value);
head = head->next;
}
printf("\n");
}

int IntValueL_getCount(IntValue *head)
{
int count = 0;
while (head !=NULL){
count++;
head = head->next;
}
return count;
}
//put at back of list
IntValue *IntValueL_insertBack(IntValue *head, IntValue *node)
{
if(head ==NULL) {
node-> next = NULL;
return node;
}
IntValue *curr = head;
while (curr ->next != NULL)
{
curr = curr->next;
}
curr->next = node;
node -> next = NULL;

}
Reverse

IntValue *new_head = NULL;
while(head !=NULL){
IntValue *tmp = head;
head = head->next;
new_head = IntValueL_insertFront(new_head,tmp);
}
return new_head;
}
Find and delete?
int IntValueL_find(IntValue *head, int value)
{
//look for integery with value == to parameter being passed in
while( head!=NULL)
{
if(head -> value ==value) {
return head;
}
head = head-> next;
}
return NULL;
}

void IntValueL_delete

Master Struct
struct IntList

int main(int argc, char **argv)
{
IntValue *head=NuLL;
head = IntValueL_insertFront(head, IntValue_create(42));
head = IntValueL_insertFront(head, IntValue_create(64));
head = IntValueL_insertFront(head, IntValue_create(128));
head = IntValueL_insertFront(head, IntValue_create(11));
//looking for and find and print
printf("Value %d is at point %p\n"
}
