X   register that will be used as the unblock signal. Use the MS_* macros
X   to build the mask and shift them 16 bits to the left. If you use more

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.
