Functions

_DN_EXP_UDP HRESULT udp_check_sockaddr (const struct sockaddr_in *sock_to, const struct sockaddr_in *sock_from)
 Checks the socket address. If sock_to and sock_from are equivalent, then returns S_OK.

 Clears the received buffer.
_DN_EXP_UDP HRESULT udp_close (int *sock)
 Closes the socket.
_DN_EXP_UDP HRESULT udp_open (void *param, int *sock)
 Opens UDP socket.
_DN_EXP_UDP HRESULT udp_recv (int sock, char *buf, uint32_t len_buf, uint32_t *len_recved, uint32_t timeout, void *arg)
 Receives UDP packet.
_DN_EXP_UDP HRESULT udp_send (int sock, const char *buf, uint32_t len_buf, void *arg)
 Sends UDP packet.
_DN_EXP_UDP HRESULT udp_set_timeout (int sock, uint32_t timeout)
 Sets timeout value to the UDP socket.
