Reading from the socket reads the client's output and printing to the socket sends data to the client. Example. Following is the example code showing its basic usage, this will check if Nagle's algorithm is turned on on a socket. Basic knowledge of Perl is required. All open handles are dup()-ed in pseudo-processes, so that closing any handles in one process does not affect the others. Perl's basic open() statement can also be used for unidirectional interprocess communication by specifying the open mode as |-or -|. Perl getsockopt Function - This function gets the socket options set on SOCKET at the socket implementation level LEVEL for the option OPTNAME.
