Hello


I was trying to generate a flow graph using file source descriptor and a file sink. But after generating the  output instead of writing to the file, it prints the output in the screen. Below is the code. Please let me know where I am going wrong.



gr::blocks::file_descriptor_source::sptr fileDescriptorSource(gr::blocks::file_descriptor_source::make(sizeof(std::complex<float>)*200000,clientSockfd,false));
 
gr::blocks::file_sink::sptr filesink(gr::blocks::file_sink::make(sizeof(std::complex<float>)*200000,"/tmp/rx.bin",false));
gr::top_block_sptr tb(gr::make_top_block("filedescriptor_test"));
 
tb->connect(fileDescriptorSource,0,filesink,0);
 
tb->start();
 
tb->wait();
