Public Member Functions

 wavfile_sink_impl (const char *filename, int n_channels, unsigned int sample_rate, int bits_per_sample)
 ~wavfile_sink_impl ()
bool open (const char *filename)
 Opens a new file and writes a WAV header. Thread-safe.
void close ()
 Closes the currently active file and completes the WAV header. Thread-safe.
void set_sample_rate (unsigned int sample_rate)
 Set the sample rate. This will not affect the WAV file currently opened. Any following open() calls will use this new sample rate.
void set_bits_per_sample (int bits_per_sample)
 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.

Member Function Documentation

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
