title: Converting bytes to uint32 in C
body: <p>I'm continuously sending arrays of pixel values (uint32) from LabVIEW to a C-program through TCP/IP. I'm using the recv function in Ws2_32.lib to receive the bytes, but I have to convert them back to uint32 data type and doesn't really know how to do it in this case. I'll be thankful if anyone shows how to do it. </p>
  
  <p>Thanks in advance</p>
