# NAME

setsockopt - set some socket options

# SYNOPSIS

setsockopt SOCKET,LEVEL,OPTNAME,OPTVAL

# DESCRIPTION

Sets the socket option requested. Returns undefined if there is an error. Use integer constants provided by the `Socket` module for LEVEL and OPNAME. Values for LEVEL can also be obtained from getprotobyname. OPTVAL might either be a packed string or an integer. An integer OPTVAL is shorthand for pack(``i'', OPTVAL).

An example disabling the Nagle's algorithm for a socket:

        use Socket qw(IPPROTO_TCP TCP_NODELAY);
        setsockopt($socket, IPPROTO_TCP, TCP_NODELAY, 1);
