Parameters

[in]	MBAY	– integer(*): BUFR message
[in]	LL	– integer: Number of last section for which the length is to be read. In other words, setting LL = N means to read and return the lengths of Sections 0 through N (i.e. LEN0, LEN1,...,LENN). Any section lengths that are not specified to be read are returned with a default placeholder value of -1.
[out]	LEN0	– integer: Length (in bytes) of Section 0
[out]	LEN1	– integer: Length (in bytes) of Section 1
[out]	LEN2	– integer: Length (in bytes) of Section 2
[out]	LEN3	– integer: Length (in bytes) of Section 3
[out]	LEN4	– integer: Length (in bytes) of Section 4
[out]	LEN5	– integer: Length (in bytes) of Section 5

Remarks

• The start of the BUFR message (i.e. the string 'BUFR') must be aligned on the first 4 bytes of MBAY.
