my_bool mysql_stmt_reset(MYSQL_STMT *stmt)
Resets a prepared statement on client and server to state after
prepare. It resets the statement on the server, data sent using
unbuffered result sets and current errors. It does not clear
bindings or stored result sets. Stored result sets will be
cleared when executing the prepared statement (or closing it).
To re-prepare the statement with another query, use
Zero if the statement was reset successfully. Nonzero if an error occurred.
