** to prevent this by setting mxPathname to a sufficiently large value.

** [[sqlite3_vfs.xAccess]]
** ^The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS]
** to test for the existence of a file, or [SQLITE_ACCESS_READWRITE] to
** test whether a file is readable and writable, or [SQLITE_ACCESS_READ]
** to test whether a file is at least readable.  The SQLITE_ACCESS_READ
** flag is never actually used and is not implemented in the built-in
** VFSes of SQLite.  The file is named by the second argument and can be a
** directory. The xAccess method returns [SQLITE_OK] on success or some
** non-zero error code if there is an I/O error or if the name of
** the file given in the second argument is illegal.  If SQLITE_OK
** is returned, then non-zero or zero is written into *pResOut to indicate
** whether or not the file is accessible.  
**
** ^SQLite will always allocate at least mxPathname+1 bytes for the
** output buffer xFullPathname.  The exact size of the output buffer
** is also passed as a parameter to both  methods. If the output buffer
** is not large enough, [SQLITE_CANTOPEN] should be returned. Since this is
** handled as a fatal error by SQLite, vfs implementations should endeavor
** to prevent this by setting mxPathname to a sufficiently large value.
