File A.txt contains:
(write-region "stuff" nil "B.txt" nil t nil t)

File B.txt is empty until I run file A.txt.


The manual says:

25.4 Writing to Files

write-region

"If visit is t, then Emacs establishes an association between the buffer and 
the file: the buffer is then visiting that file."


25.1 Visiting Files

"Visiting a file means reading a file into a buffer. Once this is done, we say 
that the buffer is visiting that file, and call the file the visited file of 
the buffer."


→ My understanding from the above manual quotes is that file B.txt is read into 
the buffer where file A.txt is.

I don't know how that should look like, but what I see is seemingly the 
opposite: full contents of file A.txt is written to file B.txt.

There is obviously something that I am missing in the documentation.
