perlfunc gods <P> pipe - open a pair of connected filehandles <P> <HR> <P> pipe <FONT SIZE=-1>READHANDLE,WRITEHANDLE</FONT> <P> <HR> <P> Opens a pair of connected pipes like the corresponding system call. Note that if you set up a loop of piped processes, deadlock can occur unless you are very careful. In addition, note that Perl's pipes use stdio buffering, so you may need to set <CODE>$|</CODE> to flush your <FONT SIZE=-1>WRITEHANDLE</FONT> after each command, depending on the application. <P> See [perlfunc:../../lib/IPC/Open2|Open2], [perlfunc:../../lib/IPC/Open3|Open3], and [%linkNodeTitle "perlman:perlipc|Bidirectional Communication", $NODE, "Bidirectional Communication",{anchor=>"Bidirectional_Communication"};%] for examples of such things. <HR>
