[openamq-dev] help on sending vector via middleware

[Malinga]

Thank you very very much for the quick reply here are the answers for the question. Hope you will help me on this.

Ok, first you have to decide how you wire-level binary format would look 
like. There are several decisions to be made:

1. Would the strings be zero-terminated or length-prefixed? If binary 
zero may occur in the middle of the string, legth-prefixing is the only 
option.

  It binary 

2. 'int' can have different number of bits depending on the system you 
are using. How many bits you want it to have on the wire?

4 bits


3. Do you want integers in big- or little- endian representation on the 
wire?

im working on the Intel platform so it will be little endian

4. How are negative integers going to be encoded on the wire?

fortunately we dont have negative numbers :) 

5. What binary encoding of floating point numbers would you choose? 
(There is a RFC for that, you may want to check it out, however, I've 
forgot the number...)

and no floats also
