CODE

 M=null_source_module(NAME, NUMCHANNELS, BLOCKSIZE, SAMPLERATE, DATATYPE, ISCOMPLEX, NUMPINS)
 This module serves as an source for unconnected wires in the layout. The
 processing function is called but performs no actual computation. This 
 module supports variable number of output pins.
 
 Arguments:
    NAME - name of the module.
    NUMCHANNELS - number of interleaved channels in each output pin.
    BLOCKSIZE - number of samples per output channel.
    SAMPLERATE - sample rate of the output signal, in Hz.
    DATATYPE - 'float', 'int', or 'fract32'
    ISCOMPLEX - 0 - no, 1 - yes
    NUMPINS - Optional: number of outputs. Default = 1 output.
