convert between native usrp format and output item format
- Parameters:
-
[out] output_items stream(s) of output items [in] output_index starting index in output_items [in] output_items_available number of empty items available at item[index] [out] output_items_produced number of items produced by copy [in] usrp_buffer source buffer [in] usrp_buffer_length number of bytes available in usrp_buffer[out] bytes_read number of bytes read from usrp_buffer
The copy must consume all bytes available. That is, bytes_read must equal usrp_buffer_length.
Implements usrp_source_base.
| virtual int usrp_source_c::ninput_bytes_reqd_for_noutput_items | ( | int | noutput_items | ) | [protected, virtual] |
return number of usrp input bytes required to produce noutput items.
Implements usrp_source_base.
