get_values

Description:

public SList<unowned Value?> get_values (int proxy_row, int[] cols_index)

This function calls gda_data_proxy_get_value for each column index specified in cols_index, and generates a SList on the way.

this	a DataProxy object
proxy_row	a proxy row
cols_index	array containing the columns for which the values are requested
n_cols	size of `cols_index`

a new list of values (the list must be freed, not the values), or null if an error occurred
