GR_UHD_API boost::shared_ptr<uhd_usrp_sink> uhd_make_usrp_sink	(	const uhd::device_addr_t &	device_addr,
		const uhd::stream_args_t &	stream_args
	)

Make a new USRP sink block.

The USRP sink block reads a stream and transmits the samples. The sink block also provides API calls for transmitter settings.

TX Stream tagging:

The following tag keys will be consumed by the work function:

• pmt::pmt_string_to_symbol("tx_sob")
• pmt::pmt_string_to_symbol("tx_eob")
• pmt::pmt_string_to_symbol("tx_time")

The sob and eob (start and end of burst) tag values are pmt booleans. When present, burst tags should be set to true (pmt::PMT_T).

The timstamp tag value is a pmt tuple of the following: (uint64 seconds, and double fractional seconds).

See the UHD manual for more detailed documentation: http://code.ettus.com/redmine/ettus/projects/uhd/wiki

Parameters:

device_addr	the address to identify the hardware
stream_args	the IO format and channel specification

Returns:

a new USRP sink block object
