Edit Question
Title
Body
I know that read() is a blocking call unless I make the socket non-blocking. So I expect read() call which requests 4K of data should return a positive value ( no of bytes read) or -1 on error ( possible connection reset by client etc). My question is: Can read() return '0' on any occasion? I am handling the read() this way: if ((readval = read(acceptfd, buf, sizeof(buf) - 1)) < 0) { } else { buf[readval] = 0; //Do some thing with data } This code bombs if read() return zero and I know how to fix it. But is it possible for read() to return zero?
