sql function: using set as argument

Hi,

I have a function that returns a set.
Looks like:
Select a_column from a_table where some_condition;

I want to use output of this function as an argument of another function
Second looks like:
Get_count(result_set_of_function_1, int)
Select count(b_column) from
some_table where some_field_1 in ($1) and some_field_2 = $2;

Please suggest how can I do that?

Regards,

akshay
