What does SQLITE_FCNTL_LAST_ERRNO do? It is not documented on the page with the rest of the op codes. https://www.sqlite.org/c3ref/c_fcntl_begin_atomic_write.html
Also, there is a bullet point on that page that just says "No longer in use." but does not indicate which op code it's referring to.

It appears to just get the errno from last I/O error.
"No longer in use" is for SQLITE_FCNTL_SYNC_OMITTED. The other oddball "Used by the cksmvfs VFS module only" is "SQLITE_FCNTL_CKSM_FILE"
