The mi_lo_tell() function
The mi_lo_tell() function returns the current LO seek position for an open smart large object, relative to the beginning of the smart large object.
Syntax
mi_integer mi_lo_tell(conn, LO_fd, seek_pos)
MI_CONNECTION *conn;
MI_LO_FD LO_fd;
mi_int8 *seek_pos;
- conn
- This value is one of the following connection values:
A pointer to a connection descriptor established by a previous call to mi_open(), mi_server_connect(), or mi_server_reconnect().
A NULL-valued pointer (database server only)
- LO_fd
- An LO file descriptor for the open smart large object whose LO seek position you want to determine.
- seek_pos
- A pointer to the eight-byte integer (mi_int8) into which mi_lo_tell() copies the current LO seek position.

Usage
The mi_lo_tell() function obtains the LO seek position for the smart large object that LO_fd references. The LO seek position is the offset for the next read or write operation on the smart large object that is associated with the LO file descriptor, LO_fd. The mi_lo_tell() function returns this seek position in the mi_int8 seek_pos variable.

Return values
- MI_OK
