Function Documentation

char* eeg_to_stream	(	const EEG *	eeg,
		char *	stream,
		ulonglong *	n
	)

convert an EEG-struct to a byte-stream. The stream can be used to pass the struct using MPI_Send, e.g.

     char *eegstream;
     long nstream;
     eegstream = eeg_to_stream( eeg, NULL, &nstream );
     MPI_Send( (void*)(eegstream), nstream, MPI_CHAR, proc,
                EEGSEND_TAG, MPI_COMM_WORLD );

Parameters:

	eeg
	stream	either enough memory to hold the stream, or NULL (allocated)
	n	is filled with the length of stream

Returns:

stream

ulonglong sizeof_channelinfos	(	const ChannelInfo *	chaninfo,
		int	nbchan
	)

Definition at line 23 of file mpitools.c.

ulonglong sizeof_eegstream

(

const EEG *

eeg

)

return the number of bytes of the bytestream created by calling eeg_to_stream.

Definition at line 33 of file mpitools.c.

EEG* stream_to_eeg	(	const char *	stream,
		ulonglong	n,
		EEG *	eeg
	)

convert stream created by eeg_to_stream() back to an EEG-struct.

Parameters:

	stream
	n	length of stream
	eeg	either an appropriate EEG-set, or NULL (allocated)

Returns:

eeg-set
