Hi Thanks for the feedback. The reason why I have to use this is because:

first I don't know what is the length of data coming. It is of variable size

second, the client is having a persistent connection to the server, which means data keeps on coming in in interval and it is of binary format. As far as I know, sysread will block if no data is coming. Thus, there is no way I could receive 0 to indicate end of file.

I understand that the timeout will backfire due to variable circumstance of network connection . Is there a reliable way which I can defintely receive the data as a whole with the condition I'm having above

Thanks!
