You will need to use non-blocking I/O if you want to do multiple reads
without hanging.
You have two options:
1. Add large static buffers and do one read.
2. Use non-blocking I/O and do multiple reads in blocks (the size can be
up to you) and dynamically allocate memory to receive an unknown size
data packet.
