Abstract
The present invention discloses a method, apparatus, and article of manufacture comprising a high performance interface for sending data to a remote device and receiving data from a remote device via a data communications device coupled to a processor. In performing these functions, the high performance interface supports asynchronous input/output operations. Moreover, the high performance interface transfers the data directly to and from the address space of a calling program, thereby eliminating use of intermediate buffers. In those instances where the calling program has not invoked the high performance interface, data can be stored in the address space of the operating system until the high performance interface is invoked by the calling computer program. Further, status can be returned to a remote device using back-channel capabilities.
