valentina_data_seek()

bool valentina_data_seek ( resource result, int row_number )

Moves the internal row pointer of the Valentina Server result associated with the specified result identifier to point to the specified row number. The next call to valentina_fetch_row() would return that row.

row_number starts at 0. The row_number should be a value in the range from 0 to valentina_num_rows() - 1. However if the result set is empty (valentina_num_rows() == 0), a seek to 0 will fail with a E_WARNING and valentina_data_seek() will return FALSE.

Returns TRUE on success or FALSE on failure.
