struct ip_globals | ip_data |
IP API
#define ip_current_dest_addr | ( | ) | (&ip_data.current_iphdr_dest) |
Destination IP address of current_header
Union destination address of current_header
#define ip_current_dest_addr | ( | ) | (&ip_data.current_iphdr_dest) |
Destination IP address of current_header
Union destination address of current_header
#define ip_current_header_tot_len | ( | ) | (ip_data.current_ip_header_tot_len) |
Total header length of ip(6)_current_header() (i.e. after this, the UDP/TCP header starts)
#define ip_current_input_netif | ( | ) | (ip_data.current_input_netif) |
Get the interface that received the current packet. This function must only be called from a receive callback (udp_recv, raw_recv, tcp_accept). It will return NULL otherwise.
#define ip_current_netif | ( | ) | (ip_data.current_netif) |
Get the interface that accepted the current packet. This may or may not be the receiving netif, depending on your netif/network setup. This function must only be called from a receive callback (udp_recv, raw_recv, tcp_accept). It will return NULL otherwise.
#define ip_current_src_addr | ( | ) | (&ip_data.current_iphdr_src) |
Source IP address of current_header
Union source address of current_header
#define ip_current_src_addr | ( | ) | (&ip_data.current_iphdr_src) |
Source IP address of current_header
Union source address of current_header
#define ip_get_option | ( | pcb, | |
opt | |||
) | ((pcb)->so_options & (opt)) |
Gets an IP pcb option (SOF_* flags)
#define IP_PCB |
This is the common part of all PCB types. It needs to be at the beginning of a PCB type definition. It is located here so that changes to this common part are made in one location instead of having to change all PCB structs.
#define ip_reset_option | ( | pcb, | |
opt | |||
) | ((pcb)->so_options = (u8_t)((pcb)->so_options & ~(opt))) |
Resets an IP pcb option (SOF_* flags)
#define ip_route_get_local_ip | ( | src, | |
dest, | |||
netif, | |||
ipaddr | |||
) |
#define ip_set_option | ( | pcb, | |
opt | |||
) | ((pcb)->so_options = (u8_t)((pcb)->so_options | (opt))) |
Sets an IP pcb option (SOF_* flags)
#define LWIP_IP_CHECK_PBUF_REF_COUNT_FOR_TX | ( | p | ) | LWIP_ASSERT("p->ref == 1", (p)->ref == 1) |
pbufs passed to IP must have a ref-count of 1 as their payload pointer gets altered as the packet is passed down the stack
