REBOL 3 Concepts: Ports: Updating a Port

Pending Revision

This document was written for R2 and has yet to be revised for R3.

The update function forces a port to update its status with respect to the external device. For example, when writing a buffered file, the update function can be used to force the data buffer out to the file. When reading, the update function can be used to be certain that any pending data has been read into memory.
