List of all members.

Public Types
typedef boost::shared_ptr < wavfile_sink >	sptr
Public Member Functions
virtual bool	open (const char *filename)=0
	Opens a new file and writes a WAV header. Thread-safe.
virtual void	close ()=0
	Closes the currently active file and completes the WAV header. Thread-safe.
virtual void	set_sample_rate (unsigned int sample_rate)=0
	Set the sample rate. This will not affect the WAV file currently opened. Any following open() calls will use this new sample rate.
virtual void	set_bits_per_sample (int bits_per_sample)=0
	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.
Static Public Member Functions
static sptr	make (const char *filename, int n_channels, unsigned int sample_rate, int bits_per_sample=16)

virtual void gr::blocks::wavfile_sink::close

(

)

[pure virtual]

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

Implemented in gr::blocks::wavfile_sink_impl.

virtual bool gr::blocks::wavfile_sink::open

(

const char *

filename

)

[pure virtual]

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

Implemented in gr::blocks::wavfile_sink_impl.

virtual void gr::blocks::wavfile_sink::set_bits_per_sample

(

int

bits_per_sample

)

[pure 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.

Implemented in gr::blocks::wavfile_sink_impl.

virtual void gr::blocks::wavfile_sink::set_sample_rate

(

unsigned int

sample_rate

)

[pure virtual]

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

Implemented in gr::blocks::wavfile_sink_impl.
