int gr::blocks::wavfile_sink_impl::bits_per_sample

(

)

void gr::blocks::wavfile_sink_impl::close ( )

virtual

Closes the currently active file and completes the WAV header. Thread-safe.

Implements gr::blocks::wavfile_sink.

bool gr::blocks::wavfile_sink_impl::open ( const char *  filename )

virtual

Opens a new file and writes a WAV header. Thread-safe.

Implements gr::blocks::wavfile_sink.

unsigned int gr::blocks::wavfile_sink_impl::sample_rate

(

)

void gr::blocks::wavfile_sink_impl::set_bits_per_sample ( int  bits_per_sample )

virtual

Set bits per sample. This will not affect the WAV file currently opened (see set_sample_rate()). If the value is neither 8 nor 16, the call is ignored and the current value is kept.

Implements gr::blocks::wavfile_sink.

void gr::blocks::wavfile_sink_impl::set_sample_rate ( unsigned int  sample_rate )

virtual

Set the sample rate. This will not affect the WAV file currently opened. Any following open() calls will use this new sample rate.

Implements gr::blocks::wavfile_sink.

int gr::blocks::wavfile_sink_impl::work ( int  noutput_items, gr_vector_const_void_star &  input_items, gr_vector_void_star &  output_items  )

virtual

just like gr_block::general_work, only this arranges to call consume_each for you

The user must override work to define the signal processing code

Implements gr_sync_block.
