How do I concatenate two binaries in Erlang?
For example, let's say I have:
B1 = <<1,2>>.
B2 = <<3,4>>.
How do I concatenate B1 and B2 to create a binary B3 which is <<1,2,3,4>>?
The reason I am asking this is because I am writing code to encode a packet for some networking protocol. I am implementing this by writing encoders for the fields in the packet and I need to concatenate those fields to build up the whole packet.
Maybe I am doing this the wrong way. Should I build up the packet as a list of integers and convert the list to a binary at the last moment?
