mi_integer mi_large_object_seek(conn, lodesc, off, whence)

		MI_CONNECTION *conn;

		MI_LODESC lodesc;

		mi_integer off;

		mi_integer whence; 


conn
is a pointer to the connection descriptor that a previous call to mi_open() or mi_server_connect() has established.

lodesc
is the descriptor of the object returned by a previous call to mi_large_object_open(). 

off
is the offset. It describes where to seek in the object. Its value depends on the value of whence. 



If whence is MI_LO_SEEK_SET, the offset is measured relative to the beginning of the object



If whence is MI_LO_SEEK_CUR, the offset is relative to the current position in the object.



If whence is MI_LO_SEEK_END, the offset is relative to the end of the file.

whence
determines how the offset is interpreted.
