mapped-file-simple-stream-buffer

Arguments: stream

Returns the buffer that has been established by the opening of the stream, which must be a subclass of mapped-file-simple-stream. This buffer will always be an aligned pointer. It is a reader only, and is thus not setf'able.

Example

This example uses sys:memref.

;; We have a file named xxx which contains a single line of text:
;;
cl-user(1): (shell "cat xxx")
abcdefgxxxxxxxxx
0
cl-user(2): (setq xxx (open "xxx" :mapped t))
#<mapped-file-simple-stream #P"xxx" mapped for input pos 0 @
  #x10003b83772>
cl-user(3): (setq buf (mapped-file-simple-stream-buffer xxx))
17461927465472
cl-user(4): (code-char (sys:memref buf 0 0 :unsigned-byte))
#\a
cl-user(5): (code-char (sys:memref buf 0 3 :unsigned-byte))
#\d
cl-user(6): (code-char (sys:memref buf 0 10 :unsigned-byte))
#\x
cl-user(7):
