Generate a general_block. Copy the content of head_impl.cc 's work() method to the general_work method. don't forget the private variables from head.h and the initialization of those in the constructor. Replace the "return -1;" by "return 0" to make the block stop producing samples after it's done it's job; before the final "return n; " add a "consume_each(n);".
