[ns] how to change the transmit power in mac-802-11.cc

[word]

thanks for  answer.
I want to control the transmit power during the sending procedure. I try to
add some code in
mac-802-11.cc.
I know using netif_ , it can get the pointer to the Phy layer, but I want to
get the wirelessPhy pointer, I do not know how to get it yet.
but I think it may the form of :
netif_->???->Pt_.
Can someone have used it,please tell me.

best regards.
