Low-Level Function Overview

Some of the low-level functions, those with return type COUNT, return an error code value. A zero error code indicates success. The rest of the index file functions, those with return type LONG, return a data record position. A zero data record position indicates an error. Each low-level function sets the value of a global error code variable: uerr_cod.

Several of the functions listed here have two versions - a standard version and an extended version. The extended version has the same name as the standard version, with a suffix of Xtd. The extended version provides access to the security features of the FairCom Server.
