FERROR()


Syntax:     FERROR()

Purpose:    To test for a DOS error after a file function.

Returns:    An integer numeric value.

            FERROR() returns the DOS error from the last file
            operation.  If there is no error, FERROR() returns zero.

            See DOSERROR() for a complete list of DOS errors.

Library:    EXTEND.LIB

            Warning: These functions allow low level access to DOS
            files and devices.  They should be used with extreme care
            and require a thorough knowledge of the operating system.
