bool LLHTTPResponder::readLine	(	const LLChannelDescriptors &	channels,
		buffer_ptr_t	buffer,
		U8 *	dest,
		S32 &	len
	)			`[protected]`

Read data off of CHANNEL_IN keeping track of last read position.

This is a quick little hack to read headers. It is not IO optimal, but it makes it easier for me to implement the header parsing. Plus, there should never be more than a few headers. This method will tend to read more than necessary, find the newline, make the front part of dest look like a c string, and move the read head back to where the newline was found. Thus, the next read will pick up on the next line.

Parameters:

	channel	The channel to read in the buffer
	buffer	The heap array of processed data
	dest	Destination for the data to be read
`[in,out]`	len	in The size of the buffer. out how much was read. This value is not useful for determining where to seek orfor string assignment.
