+ These functions operate on the system file descriptors for terminal type
+ devices. These descriptors are not related to the standard I/O FILE type-
+ def, but refer to the special device files found in _\b/_\bd_\be_\bv and named
+ _\b/_\bd_\be_\bv_\b/_\bt_\bt_\by_\bx_\bx and for which an entry exists in the initialization file
+ _\b/_\be_\bt_\bc_\b/_\bt_\bt_\by_\bs_\b. (See ttys(5).)
