my_bool mysql_stmt_close(MYSQL_STMT * stmt);
stmt- a statement handle, which was previously allocated by mysql_stmt_init().
Closes a prepared statement and deallocates the statement handle. If the current statement has pending or unread results, this function cancels them so that the next query can be executed.
Returns zero on success, nonzero on error (when communicating with the server). The statement is deallocated, regardless of the error.
If you want to reuse the statement handle with a different SQL command, use mysql_stmt_reset().
