Function Documentation

void io_destroy

(

struct io *

io

)

remove the fd from the 'mainloop' and reset all io call back, unref the io data structure

Parameters

io	pointer to the io data structure

int io_get_fd

(

struct io *

io

)

return the fd (file descriptor, can be a socket) attached to the io data structure

Parameters

io	pointer to io data structure

Returns

struct io* io_new

(

int

fd

)

create a new io data structure

Parameters

fd	file descriptor (includes socket)

Returns

NULL if error or io data structure

ssize_t io_send	(	struct io *	io,
		const struct iovec *	iov,
		int	iovcnt
	)

send data to the underlying socket (actual write)

Parameters

io	io structure which describe the underlying socket and its context
iov	pointer to pdu, pdu length structure
iovcnt	number of pdu to send (iov is an array)

Returns

The return value is a count of bytes written, or -errno indicating an error.
