pipe

NAME

pipe - open a pair of connected filehandles


SYNOPSIS

pipe READHANDLE,WRITEHANDLE


DESCRIPTION

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 $| to flush your WRITEHANDLE after each command, depending on the application.

See open2, open3, and ``Bidirectional Communication'' for examples of such things.
