>CONNECT(2)                    System Calls Manual                   CONNECT(2)
95
 
96
NAME
97
     connect - initiate a connection on a socket
98
 
99
SYNOPSIS
100
     #include &lt;sys/types.h&#62;
101
     #include &lt;sys/socket.h&#62;
102
 
103
     int
104
     connect(int s, const struct sockaddr *name, socklen_t namelen);
105
 
106
DESCRIPTION
107
     The parameter s is a socket.  If it is of type SOCK_DGRAM, this call
108
     specifies the peer with which the socket is to be associated; this
109
     address is that to which datagrams are to be sent, and the only address
110
     from which datagrams are to be received.  If the socket is of type
111
     SOCK_STREAM, this call attempts to make a connection to another socket.
112
     The other socket is specified by name, which is an address in the commu-
113
     nications space of the socket.  Each communications space interprets the
114
     name parameter in its own way.  Generally, stream sockets may success-
115
     fully connect() only once; datagram sockets may use connect() multiple
116
     times to change their association.  Datagram sockets may dissolve the
117
     association by connecting to an invalid address, such as a null address.
118
 
119
RETURN VALUES
120
     If the connection or binding succeeds, 0 is returned.  Otherwise a -1 is
121
     returned, and a more specific error code is stored in errno.
122
 
123
ERRORS
124
     The connect() call fails if:
125
 
126
     [EBADF]            S is not a valid descriptor.
127
 
128
     [ENOTSOCK]         S is a descriptor for a file, not a socket.
129
 
130
     [EADDRNOTAVAIL]    The specified address is not available on this
131
                        machine.
132
 
133
     [EAFNOSUPPORT]     Addresses in the specified address family cannot be
134
                        used with this socket.
135
 
136
     [EISCONN]          The socket is already connected.
137
 
138
     [ETIMEDOUT]        Connection establishment timed out without establish-
139
                        ing a connection.
140
 
141
     [EINVAL]           A TCP connection with a local broadcast, the all-ones
142
                        or a multicast address as the peer was attempted.
143
 
144
     [ECONNREFUSED]     The attempt to connect was forcefully rejected.
145
 
146
     [EINTR]            A connect was interrupted before it succeeded by the
147
                        delivery of a signal.
148
 
149
     [ENETUNREACH]      The network isn't reachable from this host.
150
 
151
     [EADDRINUSE]       The address is already in use.
152
 
153
     [EFAULT]           The name parameter specifies an area outside the pro-
154
                        cess address space.
155
 
156
     [EINPROGRESS]      The socket is non-blocking and the connection cannot
157
                        be completed immediately.  It is possible to select(2)
158
                        or poll(2) for completion by selecting the socket for
159
                        writing, and also use getsockopt(2) with SO_ERROR to
160
                        check for error conditions.
161
 
162
     [EALREADY]         The socket is non-blocking and a previous connection
163
                        attempt has not yet been completed.
164
 
165
     The following errors are specific to connecting names in the UNIX domain.
166
     These errors may not apply in future versions of the UNIX IPC domain.
167
 
168
     [ENOTDIR]          A component of the path prefix is not a directory.
169
 
170
     [ENAMETOOLONG]     A component of a pathname exceeded {NAME_MAX} charac-
171
                        ters, or an entire path name exceeded {PATH_MAX} char-
172
                        acters.
173
 
174
     [ENOENT]           The named socket does not exist.
175
 
176
     [EACCES]           Search permission is denied for a component of the
177
                        path prefix.
178
 
179
     [EACCES]           Write access to the named socket is denied.
180
 
181
     [ELOOP]            Too many symbolic links were encountered in translat-
182
                        ing the pathname.
