Function Documentation

int net_accept	(	int	bind_fd,
		int *	client_fd,
		unsigned char	client_ip[4]
	)

Accept a connection from a remote client.

Returns:

0 if successful, ERR_NET_ACCEPT_FAILED, or ERR_NET_WOULD_BLOCK is bind_fd was set to non-blocking and accept() is blocking.

Definition at line 200 of file net.c.

Referenced by main().

int net_bind	(	int *	fd,
		char *	bind_ip,
		unsigned int	port
	)

Create a listening socket on bind_ip:port. If bind_ip == NULL, all interfaces are binded.

Returns:

0 if successful, or one of: ERR_NET_SOCKET_FAILED, ERR_NET_BIND_FAILED, ERR_NET_LISTEN_FAILED

int net_connect	(	int *	fd,
		char *	host,

int net_recv	(	int	fd,

		int *	len
	)

Read at most 'len' characters. len is updated to reflect the actual number of characters read.

Returns:

0 if successful, ERR_NET_CONN_RESET if the connection was closed from the other side, or ERR_NET_WOULD_BLOCK if read() is blocking.

int net_send	(	int	fd,
		unsigned char *	buf,
		int *	len
	)

Write at most 'len' characters. len is updated to reflect the number of characters _not_ written.

Returns:

0 if successful, ERR_NET_CONN_RESET if the connection was closed from the other side, or ERR_NET_WOULD_BLOCK if write() is blocking.

int net_set_nonblock

(

int

fd

)

Set the socket non-blocking.

Returns:

Definition at line 241 of file net.c.

void net_usleep

(

unsigned long

usec

)

Portable usleep helper.

Note:

Real amount of time slept will not be less than select()'s timeout granularity (typically, 10ms).
