Detailed DescriptionFIFO Queue Implementation​.

---

Typedef Documentation

---

typedef struct globus_fifo_s* globus_fifo_tData type used in all function calls to manipulate a Globus FIFO

---

Function Documentation

---

globus_list_t* globus_fifo_convert_to_list (globus_fifo_t * fifo)Convert the fifo into a list​.

---

globus_fifo_t* globus_fifo_copy (const globus_fifo_t * fifo)Make a copy of the fifo​. globus_fifo_destroy() must be called the returned pointer to free memory associated with it​.

---

void* globus_fifo_dequeue (globus_fifo_t * fifo)dequeue the element at the front of the queue​.

---

void globus_fifo_destroy (globus_fifo_t * fifo)Destroy the fifo data structure​. This function destroys the memory associate with the fifo data structure​. For every call to globus_fifo_init() there must be a corresponding call to globus_fifo_destroy()

---

void globus_fifo_destroy_all (globus_fifo_t * fifo, void(*)(void *) datum_free)Destroy the fifo data structure​. This function destroys the memory associate with the fifo data structure​. It calls datum_free() on behalf of all remaining nodes in the queue​. For every call to globus_fifo_init() there must be a corresponding call to globus_fifo_destroy()

---

int globus_fifo_empty (const globus_fifo_t * fifo)This function returns a boolean indicating whether or not the fifo is empty​.

---

int globus_fifo_enqueue (globus_fifo_t * fifo, void * datum)Add data to the back of the queue​.

---

int globus_fifo_init (globus_fifo_t * fifo)Initialize the fifo structure​. This function initializes the fifo data structure​. The structure must be initalized before it can be used with any other function​.

---

int globus_fifo_move (globus_fifo_t * fifo_dest, globus_fifo_t * fifo_src)Move the queue from fifo_src pointer to fifo_dest pointer​.

---

void* globus_fifo_peek (globus_fifo_t * fifo)get a pointer to the element at the front of the queue​.

---

void* globus_fifo_remove (globus_fifo_t * headp, void * datum)remove datum from anywhere in the queue​.

---

int globus_fifo_size (const globus_fifo_t * fifo)This function returns a interger representing the number of elements in the queue​.

---

void* globus_fifo_tail_peek (globus_fifo_t * fifo)Get a pointer to the element at the back of the queue​.
