Identifier Meaning

_IMMDT

Immediate Data

_VCRC

VCRC

_ICRC

ICRC

Example:

val = GetPostHdrField (

_VCRC

); # extract VCRC field

NOTE : If there are some reserved fields in headers – they can be retrieved by using

some special keywords in header retrieving functions :

Keyword

Length

_RES_1

1 bit field

_RES_2

2 bit field

_RES_5

5 bit field

_RES_7

7 bit field

_RES_8

8 bit field

_RES_16

16 bit field

Example:

val = GetLRHField ( _RES_2 ); # extract reserved 2-bit field from LRH header

17. MAD decoded fields retrieving functions

This group of functions covers VSE capability to extract information about MAD decoded fields.

17.1 GetDecodedMADField()

Extracts information about MAD decoded field how it is shown in IBTracer trace view or
“View MAD” dialog.

Format

GetDecodedMADField (

mad_fld_name

)

Parameters:

mad_fld_name

- name of the MAD field supposedly existing in the MAD being processed:

Return Values:

The text value of the decoded field how it is seen in the trace if field name asked is present in
current MAD, empty string otherwise.
