◆ restd()

void restd	(	int	lun,
		int	tddesc,
		int *	nctddesc,
		int *	ctddesc
	)

Standardize a local Table D descriptor.

Given the bit-wise (integer) representation of a local (not WMO-standard) Table D descriptor, this subroutine returns an equivalent array of WMO-standard child descriptors.

Any child descriptors which are themselves local Table D descriptors are automatically resolved via a recursive call to this same subroutine. This recursive process continues until all child descriptors are either WMO-standard descriptors (from Table B, Table C, Table D, or replication descriptors) or else are local Table B descriptors, in which case they are preceded with an appropriate 2-06-YYY Table C operator in the output array. The output array is then useable by any standard BUFR decoder program in order to interpret the same data values as were represented by the input local Table D descriptor.

Parameters

lun	- File ID
tddesc	- WMO bit-wise representation of FXY value for local Table D descriptor
nctddesc	- Number of WMO-standard child descriptors returned in ctddesc
ctddesc	- Array of WMO-standard child descriptors equivalent to tddesc

	)

Store information about a standard Table D descriptor within internal DX BUFR tables.

Given the WMO bit-wise (integer) representation of a standard Table D descriptor, this subroutine uses the master BUFR tables to store all of the necessary information for that descriptor within the internal DX BUFR tables. Any child descriptors which are themselves Table D descriptors are automatically resolved via a recursive call to this same subroutine.

Parameters

lun	- File ID
irepct	- Replication sequence counter for the current master table; used internally to keep track of which sequence names have already been defined, and thereby avoid contention within the internal DX BUFR Table D
idn	- WMO bit-wise representation of FXY value for standard Table D descriptor
nemo	- Mnemonic corresponding to idn
cseq	- Description corresponding to idn
cdesc	- Array of WMO-standard child descriptors equivalent to idn
