Function Documentation

dsi_write()

size_t dsi_write	(	DSI *	dsi,
		void *	buf,
		const size_t	buflen )

fill up buf and then return. this should be called repeatedly until all the data has been read. i block alarm processing during the transfer to avoid sending unnecessary tickles.

dsi_writeflush()

void dsi_writeflush

(

DSI *

dsi

)

flush any unread buffers.

dsi_writeinit()

size_t dsi_writeinit	(	DSI *	dsi,
		char **	bufp )

Begin a DSI write transfer: compute the remaining data size and hand back, by reference, any payload bytes already sitting in the read-ahead buffer. bufp is valid only until the next dsi_ call that touches the socket or the read-ahead buffer; callers must consume it immediately. A NULL bufp drains the buffered payload without handing it back, for the error/flush paths that only need datasize advanced.
