CMD_READ -- return the next input from the keyboard
Read the next input, generally from the keyboard. The form of
this input is as an ANSI byte stream: i.e. either ASCII text
or control sequences. Raw input events received by the
console device can be selectively filtered via the aSRE and aRRE
control sequences (see the write command). Keys are converted
via the keymap associated with the unit, which is modified
with AskKeyMap and SetKeyMap
If, for example, raw keycodes had been enabled by writing
<CSI>1{ to the console (where <CSI> is $9B or Esc[), keys
would return raw keycode reports with the information from
the input event itself, in the form:
<CSI>1;0;<keycode>;<qualifiers>;0;0;<seconds>;<microseconds>q
If there is no pending input, this command will not be
satisfied, but if there is some input, but not as much as can
fill io_Length, the request will be satisfied with the input
currently available.
IO REQUEST
io_Message mn_ReplyPort set if quick I/O is not possible
io_Device preset by the call to OpenDevice
io_Unit preset by the call to OpenDevice
io_Command CMD_READ
io_Flags IOF_QUICK if quick I/O possible, else zero
io_Length sizeof(*buffer)
io_Data char buffer[]
a pointer to the destination for the characters to read
from the keyboard.
This function sets the error field in the IOStdReq, and fills
in the io_Data area with the next input, and io_Actual with
the number of bytes read.
