`sqlite3_createstmt` contains a variable `stmt_pos` which points to the end of the SQL already written, where the next chunk should be appended. Currently, this is assigned after every write: sprintf(stmt_pos, ...); stmt_pos = priv->stmt + strlen(priv->stmt); However, since `sprintf` returns the number of bytes written, increment `stmt_pos` by the return-value of `sprintf` in order to avoid the repeated `strlen` calls.
