status.i4.v = dio_pdb_to_display_conversion_info_c(num_pdbs.i4.v,

	This routine returns default device value conversion information for
	a PDB or a list of PDBs.

	num_pdbs	number of PDBs in list
	pdbs		PDB or array of PDBs to be analyzed
			(structure(s) of type PDB_RS)
	errors		returned ACNET status value or array of returned
			status values (A status of DBM_NOREC indicates that
			the requested PDB does not exist.)
	is_special	returned flags indicating whether or not special
			conversions from raw data are required
			(TRUE -> special conversions are required,
			 FALSE -> standard conversions used)
			(A value of NULL may be passed if this information
			 is not needed.)
	display_types	returned default display conversion types
			(constants of the form CNV_xxx which are found
			 in cbslib)
			(A value of NULL may be passed if no display types
			 are needed.)
	display_lengths	returned default display lengths
			 characters unless the common transform is a
			 special string scaling transform (60 or 84)
			 in which case the length is determined by the
			 conversion type specified in constant 0 and
			 optionally the length specified in constant 1)
			(A value of NULL may be passed if no display lengths
			 are needed.)
	handler_types	returned default raw data handler types
			(DIO_HANDLER_NONE -> no special data handling required,
			 DIO_HANDLER_SWAP_BYTES -> swap bytes,
			 DIO_HANDLER_SWAP_WORDS -> swap words)
			(A value of NULL may be passed if no handler types
			 are needed.)

	This function returns status values as follows:

	OK			success
	DIO_BADARG		invalid number of devices passed
	negative value		other ACNET format error
	positive value		number of devices in error

	This function requires the following include files:

	diolib_h, acnet_errors_h
