Fir_filter_ccc::filter function confusion


Hi, I am trying to calculate the conj(w(n))*s(n) where w(n) is the
filter weights and s(n) is the signal and Both are complex numbers. I
wanted to use fir_filter_ccc, but I noticed that it uses
volk_32fc_x2_dot_prod_32fc function to calculate the taps.

However, there is another volk function called
volk_32fc_x2_conjugate_dot_prod_32fc which I presume would be the
correct function to call.

So is this correct? Should I be using the filter function in
