Data Structures
struct	gnrc_sock_recv_aux_t
	Structure to retrieve auxiliary data from gnrc_sock_recv. More...

#define	GNRC_SOCK_DYN_PORTRANGE_MIN (IANA_DYNAMIC_PORTRANGE_MIN)
	Minimum port number in the dynamic portrange.

#define	GNRC_SOCK_DYN_PORTRANGE_MAX (IANA_DYNAMIC_PORTRANGE_MAX)
	Maximum port number in the dynamic portrange.

#define	GNRC_SOCK_DYN_PORTRANGE_NUM (GNRC_SOCK_DYN_PORTRANGE_MAX - GNRC_SOCK_DYN_PORTRANGE_MIN + 1)
	Available ports in the range for dynamic source port allocation.

#define	GNRC_SOCK_DYN_PORTRANGE_ERR (0)
	Error value indicating that no free port could be found in the dynamic port range.

#define	CONFIG_GNRC_SOCK_UDP_CHECK_REMOTE_ADDR (1)
	Check if remote address of a UDP packet matches the address the socket is bound to.

#define	GNRC_SOCK_RECV_AUX_FLAG_TIMESTAMP 0x01
	Timestamp valid.

#define	GNRC_SOCK_RECV_AUX_FLAG_RSSI 0x02
	RSSI valid.

Internal helper functions for GNRC
static bool	gnrc_af_not_supported (int af)
	Checks if address family is not supported.

static bool	gnrc_ep_addr_any (const sock_ip_ep_t *ep)
	Check if end point points to any address.

static void	gnrc_ep_set (sock_ip_ep_t out, const sock_ip_ep_t in, size_t in_size)
	Initializes a sock end-point from a given and sets the network interface implicitly if there is only one potential interface.

void	gnrc_sock_create (gnrc_sock_reg_t *reg, gnrc_nettype_t type, uint32_t demux_ctx)
	Create a sock internally.

ssize_t	gnrc_sock_recv (gnrc_sock_reg_t reg, gnrc_pktsnip_t pkt, uint32_t timeout, sock_ip_ep_t remote, gnrc_sock_recv_aux_t *aux)
	Receive a packet internally.

ssize_t	gnrc_sock_send (gnrc_pktsnip_t payload, sock_ip_ep_t local, const sock_ip_ep_t *remote, uint8_t nh)
	Send a packet internally.
