 * This file has been necessitated by the fact that the iov array is local
 * to the module, so passing the FILE ptr to a file I/O function in a
 * different module or DLL will cause the application to fail to find the
 * I/O channel and the application will terminate. The standard file I/O
 * functions are redefined to call these routines instead and there will
 * be just the one iov to deal with.

 * Outside of lib isc we need to redefine these functions
