No, primary reason to use sysread/syswrite with select, is because readline and print are not working with select.

Of course they do:

#! perl -sw use strict; use Win32::Socketpair qw[ winsocketpair ]; my( $fd1, $fd2 ) = winsocketpair(); my $v = ''; vec( $v, my $fn1 = fileno( $fd1 ), 1) = 1; vec( $v, my $fn2 = fileno( $fd2 ), 1) = 1; while( 1 ) { if( select( my $vin = $v, my $vout = $v, undef, undef ) > 0 ) { if( vec( $vout, $fn1, 1 ) ) { print( $fd1 "hello\n" ) or last; } if( vec( $vin, $fn2, 1 ) ) { defined( my $buffer = <$fd2> ) or last; print "read: $buffer"; } } } __END__ C:\test>junk88 read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello read: hello Terminating on signal SIGINT(2) read: hello

In the absence of evidence, opinion is indistinguishable from prejudice.

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.
