mutt_parse_rc_buffer()

enum CommandResult mutt_parse_rc_buffer	(	struct Buffer *	line,
		struct Buffer *	token,
		struct Buffer *	err
	)

Parse a line of user config.

Parameters

line	config line to read
token	scratch buffer to be used by parser
err	where to write error messages

Return values

CommandResult

Result e.g. MUTT_CMD_SUCCESS

The reason for token is to avoid having to allocate and deallocate a lot of memory if we are parsing many lines. the caller can pass in the memory to use, which avoids having to create new space for every call to this function.
