This request is used to obtain one or more character data records from the Keyboard Input buffer (KIB) for the session of the currently active process. The CharData Record is not removed from the KIB. Notice that if shift report is on, then the CharData Record might not contain a character; instead, it could contain a shift state change in the Shift Status field.

This function returns an UNKNOWN_COMMAND error if the caller is in the Presentation Manager session.
