Node:Connecting, Next:Listening, Up:Connections
In making a connection, the client makes a connection while the server
waits for and accepts the connection. Here we discuss what the client
program must do with the connect
function, which is declared in
sys/socket.h
.
int connect (int socket, struct sockaddr *addr, socklen_t length) | Function |
The connect function initiates a connection from the socket
with file descriptor socket to the socket whose address is
specified by the addr and length arguments. (This socket
is typically on another machine, and it must be already set up as a
server.) See Socket Addresses, for information about how these
arguments are interpreted.
Normally, connect waits until the server responds to the request
before it returns. You can set nonblocking mode on the socket
socket to make connect return immediately without waiting
for the response. See File Status Flags, for information about
nonblocking mode.
The normal return value from connect is 0 . If an error
occurs, connect returns -1 . The following errno
error conditions are defined for this function:
