X/* This structure contains everything one would like to know about
X an open device. There is one of it for each physical unit.
X
X We use several unions to eliminate most integer type conversions
X at run-time. The standard UNIX V 3.X/386 C compiler forces all
X operands in expressions and all function parameters to type int.
X To save some time, with the means of unions we deliver type int
X at the proper locations while dealing with the original type
X wherever int would be slower.
X
X This is highly compiler implementation specific. But for the sake
X of speed the end justifies the means.
X
X Take care that the size of the area that contains the various
X structure fields (up to, but excluding the ring buffers)
X is <= 128 bytes. Otherwise a 4-byte offset is used to access
X some of the structure fields. For the first 128 bytes a 1-byte
X offset is used, which is faster.
