If there are severals filehandles parallel at the same time, I can do a loop and next to read the filehandels. Here I just use a simple example to try non-blocking and sysread. So just one filehandle, set to non blocking, then read.

In reply to Re^2: use sysread to read non-blocking filehandle by x12345
in thread use sysread to read non-blocking filehandle by x12345
