Macro Definition Documentation

◆ lws_start_foreach_ll

#define lws_start_foreach_ll	(	type,
		it,
		start )

#include <include/libwebsockets/lws-dll2.h>

Value:

{ \
        type it = start; \
        while (it) {

lws_start_foreach_ll(): linkedlist iterator helper start

Parameters

type	type of iteration, eg, struct xyz *
it	iterator var name to create
start	start of list

This helper creates an iterator and starts a while (it) { loop. The iterator runs through the linked list starting at start and ends when it gets a NULL. The while loop should be terminated using lws_start_foreach_ll().

Definition at line 44 of file lws-dll2.h.

#define lws_start_foreach_ll(type, it, start)\
{ \
        type it = start; \
        while (it) {

◆ lws_end_foreach_ll

#define lws_end_foreach_ll	(		it,
			nxt )

#include <include/libwebsockets/lws-dll2.h>

Value:

                it = it->nxt; \
        } \
}

lws_end_foreach_ll(): linkedlist iterator helper end

Parameters

it	same iterator var name given when starting
nxt	member name in the iterator pointing to next list element

This helper is the partner for lws_start_foreach_ll() that ends the while loop.

Definition at line 59 of file lws-dll2.h.

#define lws_end_foreach_ll(it, nxt) \
                it = it->nxt; \
        } \
}

◆ lws_start_foreach_ll_safe

#define lws_start_foreach_ll_safe	(	type,
		it,
		start,
		nxt )

#include <include/libwebsockets/lws-dll2.h>

Value:

{ \
        type it = start; \
        while (it) { \
                type next_##it = it->nxt;

lws_start_foreach_ll_safe(): linkedlist iterator helper start safe against delete

Parameters

type	type of iteration, eg, struct xyz *
it	iterator var name to create
start	start of list
nxt	member name in the iterator pointing to next list element

This helper creates an iterator and starts a while (it) { loop. The iterator runs through the linked list starting at start and ends when it gets a NULL. The while loop should be terminated using lws_end_foreach_ll_safe(). Performs storage of next increment for situations where iterator can become invalidated during iteration.

Definition at line 79 of file lws-dll2.h.

#define lws_start_foreach_ll_safe(type, it, start, nxt)\
{ \
        type it = start; \
        while (it) { \
                type next_##it = it->nxt;

◆ lws_end_foreach_ll_safe

#define lws_end_foreach_ll_safe ( it )

#include <include/libwebsockets/lws-dll2.h>

Value:

                it = next_##it; \
        } \
}

lws_end_foreach_ll_safe(): linkedlist iterator helper end (pre increment storage)

Parameters

it	same iterator var name given when starting

This helper is the partner for lws_start_foreach_ll_safe() that ends the while loop. It uses the precreated next_ variable already stored during start.

Definition at line 95 of file lws-dll2.h.

#define lws_end_foreach_ll_safe(it) \
                it = next_##it; \
        } \
}

◆ lws_start_foreach_llp

#define lws_start_foreach_llp	(	type,
		it,
		start )

#include <include/libwebsockets/lws-dll2.h>

Value:

{ \
        type it = &(start); \
        while (*(it)) {

lws_start_foreach_llp(): linkedlist pointer iterator helper start

Parameters

type	type of iteration, eg, struct xyz **
it	iterator var name to create
start	start of list

This helper creates an iterator and starts a while (it) { loop. The iterator runs through the linked list starting at the address of start and ends when it gets a NULL. The while loop should be terminated using lws_start_foreach_llp().

This helper variant iterates using a pointer to the previous linked-list element. That allows you to easily delete list members by rewriting the previous pointer to the element's next pointer.

Definition at line 116 of file lws-dll2.h.

#define lws_start_foreach_llp(type, it, start)\
{ \
        type it = &(start); \
        while (*(it)) {

#define lws_start_foreach_llp_safe	(	type,
		it,

Value:

{ \
        type it = &(start); \
        type next; \
        while (*(it)) { \
                next = &((*(it))->nxt); \

◆ lws_end_foreach_llp

#define lws_end_foreach_llp	(		it,

#include <include/libwebsockets/lws-dll2.h>

Value:

                it = &(*(it))->nxt; \
        } \
}

lws_end_foreach_llp(): linkedlist pointer iterator helper end

Parameters

it	same iterator var name given when starting
