Field Documentation

uint16_t ltrx_udp_socket_options::optLocalPort

[in] If non-zero, specifies the local port. If 0, a random unused UDP port number will be assigned.

void(* ltrx_udp_socket_options::optNewConnectionCallback)(void *opaque, const struct ltrx_ip_address *remoteAddress, uint16_t remotePort)

[in] If present, the function will be called when the UDP socket receives a packet from a different remote address or port. Otherwise, fill in NULL.

void* ltrx_udp_socket_options::optOpaque

[in] If and when optNewConnectionCallback is called, its "opaque" parameter will be filled in with this value.

void(* ltrx_udp_socket_options::optReceiveCallback)(struct ltrx_ip_socket *)

[in] If present, the function will be called when data is received. Otherwise, fill in NULL.

struct ltrx_trigger* ltrx_udp_socket_options::optReceiveEventTrigger

[in] If present, the specified trigger will subsequently be signaled when data is received. Otherwise, fill in NULL.

const char* ltrx_udp_socket_options::optRemoteAddress

[in] If non-NULL, names a destination address.

uint16_t ltrx_udp_socket_options::optRemotePort

[in] If non-0, specifies a remote port.

bool ltrx_udp_socket_options::receptionIsRestricted

[in] If true, received packets whose from address and port do not match the designated remote address and port will be discarded. In listen mode, the remote address and port of the first received packet are taken as designated until the socket is closed.

uint8_t ltrx_udp_socket_options::zeroBasedInterface

[in] Index for the desired interface (if available on the platform).

  • NETS_SOFTAP_START for ap0.
  • NETS_ETHERNET_START for eth0.
  • NETS_WLAN_START for wlan0.
