Field Documentation

sin_family

sa_family_t sockaddr_in::sin_family

Socket address family (part of struct sockaddr)

Always set to AF_INET for IPv4 addresses

Definition at line 87 of file in.h.

Referenced by dns_xfer_deliver(), pxe_udp_deliver(), slam_open(), start_dhcp(), and start_pxebs().

sin_flags

uint16_t sockaddr_in::sin_flags

Flags (part of struct sockaddr_tcpip)

Definition at line 89 of file in.h.

sin_port

uint16_t sockaddr_in::sin_port

TCP/IP port (part of struct sockaddr_tcpip)

Definition at line 91 of file in.h.

Referenced by gdbudp_configure(), gdbudp_recv(), gdbudp_send(), pxe_udp_deliver(), pxenv_udp_write(), start_dhcp(), start_pxebs(), and tftp_set_mtftp_port().

sin_scope_id

uint16_t sockaddr_in::sin_scope_id

Scope ID (part of struct sockaddr_tcpip)

For multicast addresses, this is the network device index.

Definition at line 96 of file in.h.

Referenced by ipv4_netdev(), and ipv4_tx().

sin_addr

struct in_addr sockaddr_in::sin_addr

IPv4 address.

Definition at line 98 of file in.h.

Referenced by comboot_resolv_done(), dhcp_request_rx(), dhcp_tx(), dns_xfer_deliver(), gdbudp_configure(), gdbudp_recv(), gdbudp_send(), ipv4_netdev(), ipv4_sock_aton(), ipv4_sock_ntoa(), ipv4_tx(), nslookup_resolv_done(), pxe_udp_deliver(), pxenv_udp_open(), start_pxebs(), tftp_set_mtftp_address(), and x509_check_ipaddress().

pad

char sockaddr_in::pad[sizeof(struct sockaddr) -(sizeof(sa_family_t)+ sizeof(uint16_t)+ sizeof(uint16_t)+ sizeof(uint16_t)+ sizeof(struct in_addr))]

Padding.

This ensures that a struct sockaddr_in is large enough to hold a socket address for any TCP/IP address family.
