Arguments

 

keyboard-id

   OpenVMS usage:identifier
   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference

   Keyboard identifier. The keyboard-id argument is the address of
   an unsigned longword containing the identifier of the virtual
   keyboard from which to read.

   Create a virtual keyboard by calling the SMG$CREATE_VIRTUAL_
   KEYBOARD routine.
 

keyboard-info-table

   OpenVMS usage:unspecified
   type:         unspecified
   access:       write only
   mechanism:    by reference, array reference

   Receives the keyboard attributes. The keyboard-info-table
   argument is the address of a data block into which the keyboard
   attributes are written.

   The KIT is a byte block whose size and field references are
   described in $SMGDEF. It is the caller's responsibility to
   allocate the correct size block and to pass its address to this
   routine.

   The values in the keyboard-info-table can be accessed through the
   following symbolic names:

   SMG$L_DEV_CHAR     Device characteristics (longword)
   SMG$L_DEV_DEPEND   Specific characteristics 1 (longword)
   SMG$L_DEV_DEPEND2  Specific characteristics 2 (longword)
   SMG$L_DEV_DEPEND3  Specific characteristics 3 (longword)
   SMG$B_DEV_CLASS    Device class (byte) - for example, DC$_TERM
   SMG$B_RECALL_NUM   Size of recall buffer (byte)*
   SMG$B_DEVTYPE      Physical device type (byte) - for example,
                      TT$_VT100
   SMG$B_TYPEAHD_     First character in type-ahead buffer (byte)*
   CHAR
   SMG$W_NUM_COLUMNS  Terminal width (word)
   SMG$W_TYPEAHD_CNT  Number of characters in type-ahead buffer
                      (word)*

   Items marked with an asterisk (*) will be zero unless the device
   is a terminal (DEVCLASS = DC$_TERM).
 

keyboard-info-table-size

   OpenVMS usage:longword_unsigned
   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference

   Size of the keyboard information table. The keyboard-info-table-
   size argument is the address of an unsigned longword containing
   the size of the KIT in bytes.

   The size you specify must be exact. You can specify this size
   with the symbolic constant SMG$C_KEYBOARD_INFO_BLOCK.
