Re^4: Using read/syswrite with IO::Socket::SSL

O.k., can_read() takes a timeout value as an argument and if that it set to 0, it will not block. I understand.

According to the docs it returns a list of handles that are ready for reading.

Is it correct that I have to traverse this list and check whether $sock is amongst them to fulfil the condition You stated?

->can_read(0) will only return handles that have been set into the IO::Select object. Only set those you are interested in. BTW, from the fragment you gave, $sock is your listen socket and is only used for accepts. $client_sock is your read/write socket. typical code fragment: `for my $handle ( $sel->can_read(0) ) { if( $handle == $sock ) { # do accepts here... } elsif( $handle == $client_sock ) { # do sysreads here... } }` [download]	[reply] [d/l]

typical code fragment:

for my $handle ( $sel->can_read(0) )
  {
  if( $handle == $sock )
    {
    # do accepts here...
    }
  elsif( $handle == $client_sock )
    {
    # do sysreads here...
    }
  }
