Macro Definition Documentation

FD_CLR

#define FD_CLR	(		n,
			p )

Value:

((p)->fd_bits[((n) - LWIP_SOCKET_OFFSET) / 8] = (unsigned char) ((p)->fd_bits[((n) - LWIP_SOCKET_OFFSET) / 8] & ~(1u << (((n) - LWIP_SOCKET_OFFSET) & 7))))

Clear a socket descriptor from an fd_set.

FD_ISSET

#define FD_ISSET	(		n,
			p )

Value:

(((p)->fd_bits[((n) - LWIP_SOCKET_OFFSET) / 8] & (1u << (((n) - LWIP_SOCKET_OFFSET) & 7))) != 0)

Return whether a socket descriptor is present in an fd_set.

FD_SET

#define FD_SET	(		n,
			p )

Value:

((p)->fd_bits[((n) - LWIP_SOCKET_OFFSET) / 8] = (unsigned char) ((p)->fd_bits[((n) - LWIP_SOCKET_OFFSET) / 8] | (1u << (((n) - LWIP_SOCKET_OFFSET) & 7))))

Mark a socket descriptor as present in an fd_set.

FD_ZERO

#define FD_ZERO

(

p

)

Value:

memset((void *) (p), 0, sizeof(*(p)))

Reset an fd_set so that it tracks no descriptors.

select

#define select	(		maxfdp1,
			readset,
			writeset,
			exceptset,
			timeout )

Value:

lwip_select(maxfdp1, readset, writeset, exceptset, timeout)

Route select calls through the lwIP compatibility shim on nxdk builds.

Function Documentation

lwip_recv()

ssize_t lwip_recv	(	int	s,
		void *	mem,
		size_t	len,
		int	flags )

Receive bytes through the lwIP socket backend.

Parameters

s	lwIP socket descriptor.
mem	Destination buffer.
len	Maximum number of bytes to receive.
flags	lwIP receive flags.

Returns

Number of bytes received, or a negative value on failure.

lwip_select()

int lwip_select	(	int	maxfdp1,
		struct fd_set *	readset,
		struct fd_set *	writeset,
		struct fd_set *	exceptset,
		struct timeval *	timeout )

Wait for lwIP socket readiness using the nxdk select implementation.

Parameters

maxfdp1	One greater than the highest descriptor to inspect.
readset	Optional descriptor set watched for readability.
writeset	Optional descriptor set watched for writability.
exceptset	Optional descriptor set watched for exceptional conditions.
timeout	Optional timeout value.

Returns

Number of ready descriptors, zero on timeout, or a negative value on failure.

lwip_send()

ssize_t lwip_send	(	int	s,
		const void *	dataptr,
		size_t	size,
		int	flags )

Send bytes through the lwIP socket backend.

Parameters

s	lwIP socket descriptor.
dataptr	Source buffer.
size	Number of bytes to send.
flags	lwIP send flags.

Returns

Number of bytes sent, or a negative value on failure.
