ABSTRACT:
An improved computer program method for rapidly copying data that operates in a time-shared operating system environment. Two concurrent computer program processes are employed, each copying data from the input device to the output device through its own memory buffer. The two processes communicate with one another through interprocess communication means provided by the operating system in order to coordinate their activity. As a result, double buffered overlapped input/output is achieved using only synchronous input/output commands provided by the operating system.
