3.4.1 IOSTREAM Class Usage

OBJECT IOS[IOSTREAM];

The IOSTREAM class implements fully buffered I/O streams.

I/O streams provide a string/character-oriented interface to the programmer while performing block-oriented I/O to the file or device associated with a stream. This way, they combine the speed of block-I/O with the flexibility of character-based I/O.

This class contains the I/O stream data structure and procedures for creating, opening, closing, reading, and writing streams.

A separate IOSTREAM object must be defined for each stream to be used in a program.
