SYNTAX

(SEND <gobj> :BYTE-ADJUST-ARRAY <fix:newsize>)  ; 0 <= nex
(SEND <gobj> :BYTE-AREF <fix:index>)            ; 0 <= Index < size
(SEND <gobj> :BYTE-ARRAY-DIMENSION)
(SEND <gobj> :BYTE-SETF <fix:index> <fix:val>)

DESCRIPTION

Fetch or store bytes from binary segment; Get or set size-in-bytes of binary segment. Valid indices are always 0 to BYTE-ARRAY-DIMENSION -1.

EXAMPLES

(setq g (send class-gobject :new))  ; Create a gobject instance.
(send g :byte-adjust-array 2))      ; Expand binary segment to two bytes.
(send g :byte-setf  0 5))           ; Set first byte in segment to 5.
(send g :byte-aref  0))             ; Read back first byte.
