|

<p>
|
|
If X is the name of a rollback or WAL-mode journal file that is
|
|
passed into the xOpen method of <a href="../c3ref/vfs.html">sqlite3_vfs</a>, then
|
|
sqlite3_database_file_object(X) returns a pointer to the <a href="../c3ref/file.html">sqlite3_file</a>
|
|
object that represents the main database file.</p>
|
|
|
|
<p>This routine is intended for use in custom <a href="../vfs.html">VFS</a> implementations
|
|
only. It is not a general-purpose interface.
|
|
The argument sqlite3_file_object(X) must be a filename pointer that
|
|
has been passed into <a href="../c3ref/vfs.html">sqlite3_vfs</a>.xOpen method where the
|
|
flags parameter to xOpen contains one of the bits
|
|
<a href="../c3ref/c_open_autoproxy.html">SQLITE_OPEN_MAIN_JOURNAL</a> or <a href="../c3ref/c_open_autoproxy.html">SQLITE_OPEN_WAL</a>. Any other use
|
|
of this routine results in undefined and probably undesirable
|
|
behavior.
