pNA+ System Calls connect
connect Initiates a connection on a socket.
#include
long connect(
int s, /* socket descriptor */
struct sockaddr_in *addr, /* socket attributes */
int addrlen /* attribute size */
)
Description
Arguments
This system call is used to establish an association between a local socket and a
foreign socket.
Generally, a stream socket connects only once. A datagram socket can use
connect() multiple times to change its association. A datagram socket can
dissolve the association by connecting to an invalid address, such as the null
address INADDR_ANY defined in pna.h.
If a stream socket is specified, connect() initiates a connection request to the
foreign socket. The caller is blocked until a connection is established, unless the
socket is non-blocking.
If a datagram socket is specified, connect() associates the socket with the socket
address supplied. This address is used by future send() calls to determine the
datagram's destination. This is the only address from which datagrams can be
received.
If a raw socket is specified, connect() associates the socket with the socket
address supplied. This address is used by future send() calls to determine the
datagram's destination. This is the only address from which datagrams can be
received.
s Specifies the local socket.
