Function/Subroutine Documentation

upds3()

recursive subroutine upds3	(	dimension(*)	MBAY,
			LCDS3,
		character*6, dimension(*)	CDS3,
			NDS3
	)

This subroutine returns the sequence of data descriptors contained within Section 3 of a BUFR message.

Remarks

• The start of the BUFR message (i.e. the string 'BUFR') must be aligned on the first 4 bytes of MBAY.
• This subroutine does not recursively resolve any Table D descriptors from within Section 3; rather, what is returned in CDS3 is the exact list of data descriptors as it appears within Section 3 of MBAY.

Parameters

[in]	MBAY	- integer(*): BUFR message.
[in]	LCDS3	- integer: Dimensioned size (in integers) of CDS3 in the calling program; used by the subroutine to ensure that it doesn't overflow the CDS3 array.
[out]	CDS3	- character*6(*): Data descriptor sequence within Section 3 of MBAY.
[out]	NDS3	- integer: Number of data descriptors in CDS3.
