68 Managing descriptor references
70 A duplicate of a descriptor reference may be made by doing
75 returning a copy of descriptor reference \fIold\fP indistinguishable from
77 smallest unused descriptor reference slot.
78 A copy of a descriptor reference may be made in a specific slot
84 The \fIdup2\fP call causes the system to deallocate the descriptor reference
86 to the same descriptor as old.
129 A descriptor selects for input if an input oriented operation
133 A descriptor selects for output if an output oriented operation
138 A descriptor selects for an exceptional condition if a condition
