Member Function Documentation

virtual void usrp1_source_s::copy_from_usrp_buffer	(	gr_vector_void_star &	output_items,
		int	output_index,
		int	output_items_available,
		int &	output_items_produced,
		const void *	usrp_buffer,
		int	usrp_buffer_length,
		int &	bytes_read
	)			[protected, virtual]

convert between native usrp format and output item format

Parameters:

	output_items[out]	stream(s) of output items
	output_index[in]	starting index in output_items
	output_items_available[in]	number of empty items available at item[index]
	output_items_produced[out]	number of items produced by copy
	usrp_buffer[in]	source buffer
	usrp_buffer_length[in]	number of bytes available in usrp_buffer
	bytes_read[out]	number of bytes read from usrp_buffer

The copy must consume all bytes available. That is, bytes_read must equal usrp_buffer_length.

Implements usrp1_source_base.

virtual int usrp1_source_s::ninput_bytes_reqd_for_noutput_items

(

int

noutput_items

)

[protected, virtual]

return number of usrp input bytes required to produce noutput items.

Implements usrp1_source_base.
