  64 .Sh DESCRIPTION
  65 The
  66 .Fn cfgetispeed
  67 function extracts the input baud rate from the
  68 .Vt termios
  69 structure to which the
  70 .Fa termios_p
  71 argument points.
  72 .Pp
  73 The
  74 .Fn cfgetospeed
  75 function extracts the output baud rate from the
  76 .Vt termios
  77 structure to which the
  78 .Fa termios_p
  79 argument points.
  80 .Pp
  81 These functions return exactly the value in the
  82 .Vt termios
  83 data structure, without interpretation.
  84 .Sh RETURN VALUES
  85 Upon successful completion,
  86 .Fn cfgetispeed
  87 returns a value of type
  88 .Vt speed_t
  89 representing the input baud rate.
  90 .Pp
  91 Upon successful completion,
  92 .Fn cfgetospeed
  93 returns a value of type
  94 .Vt speed_t
  95 representing the output baud rate.
