Function Documentation

static int file_write	(	FILE *	file,
		void *	buf,
		int	len
	)			[static]

A CCSDS_ostream output callback routine used when writing the specified buffer to a file.

Return values:

0,to

satisfy the interface requriements of CCSDS_ostream

Parameters:

	file	The output file handle
	buf	The buffer to write
	len	The number of bytes in buffer to write

void filter_sdi_construct	(	FilterSdi *	sdi,
		const char *	ofilename
	)

Construct the output configuration structure.

Parameters:

	sdi	The science device interface handle
	ofilename	The name of the output file, may be HULL in which case no output file is written
