Detailed Description

Macro Definition Documentation

IP4_ADDR_ANY

#define IP4_ADDR_ANY   (&ip_addr_any)

Can be used as a fixed/const ip_addr_t for the IPv4 wildcard and the broadcast address

IP4_ADDR_ANY4

#define IP4_ADDR_ANY4   (ip_2_ip4(&ip_addr_any))

Can be used as a fixed/const ip4_addr_t for the wildcard and the broadcast address

IP4_ADDR_BROADCAST

#define IP4_ADDR_BROADCAST   (ip_2_ip4(&ip_addr_broadcast))

ip_2_ip4

#define ip_2_ip4

(

ipaddr

)

(&((ipaddr)->u_addr.ip4))

Convert generic ip address to specific protocol version

IP_ADDR4

#define IP_ADDR4	(		ipaddr,
			a,
			b,
			c,
			d
	)

Value:

do { IP4_ADDR(ip_2_ip4(ipaddr),a,b,c,d); \
                                           IP_SET_TYPE_VAL(*(ipaddr), IPADDR_TYPE_V4); } while(0)

IP_ADDR_ANY

#define IP_ADDR_ANY   IP4_ADDR_ANY

Can be used as a fixed/const ip_addr_t for the IP wildcard. Defined to IP4_ADDR_ANY when IPv4 is enabled. Defined to IP6_ADDR_ANY in IPv6 only systems. Use this if you can handle IPv4 AND IPv6 addresses. Use IP4_ADDR_ANY or IP6_ADDR_ANY when the IP type matters.

IP_ADDR_BROADCAST

#define IP_ADDR_BROADCAST   (&ip_addr_broadcast)

ip_addr_copy_from_ip4

#define ip_addr_copy_from_ip4	(		dest,
			src
	)

Value:

do{ \
  ip4_addr_copy(*ip_2_ip4(&(dest)), src); IP_SET_TYPE_VAL(dest, IPADDR_TYPE_V4); }while(0)

ip_addr_get_ip4_u32

#define ip_addr_get_ip4_u32

(

ipaddr

)

Value:

(((ipaddr) && IP_IS_V4(ipaddr)) ? \
  ip4_addr_get_u32(ip_2_ip4(ipaddr)) : 0)

ip_addr_set_ip4_u32

#define ip_addr_set_ip4_u32	(		ipaddr,
			val
	)

Value:

do{if(ipaddr){ip4_addr_set_u32(ip_2_ip4(ipaddr), val); \
  IP_SET_TYPE(ipaddr, IPADDR_TYPE_V4); }}while(0)

IP_IS_V4

#define IP_IS_V4

(

ipaddr

)

(((ipaddr) == NULL) || IP_IS_V4_VAL(*(ipaddr)))

IP_IS_V4_VAL

#define IP_IS_V4_VAL

(

ipaddr

)

(IP_GET_TYPE(&ipaddr) == IPADDR_TYPE_V4)

IPADDR4_INIT

#define IPADDR4_INIT

(

u32val

)

{ { { { u32val, 0ul, 0ul, 0ul } } }, IPADDR_TYPE_V4 }

IPADDR4_INIT_BYTES

#define IPADDR4_INIT_BYTES	(		a,
			b,
			c,
			d
	)		IPADDR4_INIT(PP_HTONL(LWIP_MAKEU32(a,b,c,d)))
