recv
recv socket, $var, len, flags
Receives a message on a socket. It attempts to
receive len
bytes of data into variable
var
from the specified
socket
filehandle. The function returns
the address of the sender, or the undefined value if there’s an
error. var
will grow or shrink to the
length actually read. The function takes the same flags as the
recv(2)
system call.
