mi_integer mi_last_serial8(conn, serial8_val)
MI_CONNECTION *conn;

Valid in client LIBMI application? Valid in user-defined routine? Yes Yes
Usage
The database server automatically generates a value for a SERIAL8 column when it executes an INSERT statement on the column.
Server only: Use
the mi_last_serial8() function to obtain the last
system-generated SERIAL8 value for your C user-defined routine.
Client only: To use the mi_last_serial8() function
in a client LIBMI application, call it after the insert operation
is complete (when the mi_get_result() function
returns the MI_DML statement).
You must also call mi_last_serial8() before any call to mi_query_finish() or mi_close().
Return values
- MI_OK
- The function was successful.
- MI_ERROR
- The function was not successful.
