Abstract:
|
|
|
|
This file contains structures and defines that are used
|
|
specifically for the tape drivers. Contains #define's,
|
|
function protypes, etc. for use in calling functions in
|
|
physlogi.c that do physical to pseudo-logical and pseudo-
|
|
logical to physical tape block address/position translation.
