You can download below a VC++ project example of using the OSS ASN.1 Tools for C. This example illustrates how you can automatically encode and decode the H4501SupplementaryService PDU and print all its components.
The original file H4501-Supplementary-ServiceAPDU-Structure.asn was missing the OPERATIONS information object set. It was empty. So the OPERATIONS information object was added to make it possible to automatically encode/decode the inner sub-PDU carried by OpenType.
Note that the following ASN.1/C compiler command line was used:
asn1 *.asn -root -per -extern dav -out dav
Also added was dir.asn to apply a global OSS directive to change ERROR to MyERROR to avoid the VC++ name conflict.
