In his book The Humane Interface, Jef Raskin defines modality as follows: "An human-machine interface is modal with respect to a given gesture when (1) the current state of the interface is not the user's locus of attention and (2) the interface will execute one among several different responses to the gesture, depending on the system's current state."

Technically, the term "cooked mode" should be associated only with streams that have a terminal line discipline , but generally it is applied to any system that does some amount of preprocessing.

Operations on the file, such as a write, can be seen by operations on the other descriptors: a later read can read the newly written data. During the open, the filesystem may allocate memory for buffers, or it may wait until the first operation. The absolute file path is resolved. This may include connecting to a remote host and notifying an ...
