如何使用Avro C ++库读取具有字节模式的Avro文件

Question

I have a avro file that doesn't have a JSON schema. All it has is a single field called "bytes" and the value is just binary representation of some object which I can decode. The first few bytes of the avro looks like;

bash-4.1$ hexdump -c ped.avro -n 32
0000000   O   b   j 001 002 026   a   v   r   o   .   s   c   h   e   m
0000010   a 016   "   b   y   t   e   s   "  \0   [ 346   Q 266 266 207

Anyone familiar with Avro C or Avro C++ libraries, can answer how to read these bytes field?

I don't believe there is any way to read AVRO data with the AVRO C or C++ libraries if you have no schema. AVRO is always supposed to have a schema and without it there are any number of possible schemas that could fit the data.
