How do I encode a message?

To encode a message, you need to fill a compiler-generated variable or structure that has a #defined PDU macro constant with your message. Next, you have to initialize an instance of the OssBuf type to serve as the output buffer for the encoder. Lastly, you pass the filled instance of the unencoded PDU structure along with its #defined PDU macro constant and the initialized OssBuf output variable to the ossEncode() function. This function will then fill the output buffer with a stream of bits representing the encoding corresponding to the message you sent.

For an illustration of this process, please refer to the example C program in the OSS ASN.1/C API Runtime Reference Manual (in section 10.1 of the April 2011 edition).
