Excerpt
General Overview: The common file library is a set of routines that provide access to a file structure hereafter called the common file. The common file structure is a third generation attempt to provide a unifying file structure for storing CFD data. It provides a flexible and extendable mechanism for storing CFD and other data as well. The purpose of the common file library is to insulate the applications programmer from the nuances of dealing with the myriad of different computer types that make up a computing system. By using the library the application programmer can process a common file from another machine without having to perform explicit conversions...
