Using sysread(), your indication that the other end has closed the connection would be a "successful sysread of zero bytes". This works when the other end does an orderly close() or shutdown() of the send side of the socket. So, you would have to test the return value of sysread() for undef (error) and zero( end of file, a.k.a, client closed connection ).

In the event that something unusual happens ( perhaps the client crashed ?), keepalives could be helpful. ($sockobj->sockopt(SO_KEEPALIVE,1);)

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
