bool gr::analog::ctcss_squelch_ff_impl::gate ( ) const

inlinevirtual

Implements gr::analog::ctcss_squelch_ff.

References gr::analog::squelch_base_ff_impl::gate().

int gr::analog::ctcss_squelch_ff_impl::general_work ( int  noutput_items, gr_vector_int &  ninput_items, gr_vector_const_void_star &  input_items, gr_vector_void_star &  output_items  )

inlinevirtual

compute output items from input items

Parameters

noutput_items	number of output items to write on each output stream
ninput_items	number of input items available on each input stream
input_items	vector of pointers to the input items, one entry per input stream
output_items	vector of pointers to the output items, one entry per output stream

Returns

number of items actually written to each output stream, or -1 on EOF. It is OK to return a value less than noutput_items. -1 <= return value <= noutput_items

general_work must call consume or consume_each to indicate how many items were consumed on each input stream.
