The \&\f(CW\*(C`cid\*(C'\fR and \f(CW\*(C`port\*(C'\fR parameters specify the server address. Usually \&\f(CW\*(C`cid\*(C'\fR should be \f(CW2\fR (to connect to the host), and \f(CW\*(C`port\*(C'\fR might be \&\f(CW10809\fR or another port number assigned to you by the host administrator. This call returns when the connection has been made. .SH "RETURN VALUE" .IX Header "RETURN VALUE" If the call is successful the function returns \f(CW0\fR. .SH "ERRORS" .IX Header "ERRORS" On error \f(CW\*(C`\-1\*(C'\fR is returned. .PP Refer to \*(L"\s-1ERROR HANDLING\*(R"\s0 in \fBlibnbd\fR\|(3) for how to get further details of the error. .SH "HANDLE STATE" .IX Header "HANDLE STATE" The handle must be newly created, otherwise this call will return an error. .SH "VERSION" .IX Header "VERSION" This function first appeared in libnbd 1.2. .PP If you need to test if this function is available at compile time check if the following macro is defined: .PP .Vb 1 \& #define LIBNBD_HAVE_NBD_CONNECT_VSOCK 1 .Ve .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBnbd_create\fR\|(3), \&\fBlibnbd\fR\|(3). .SH "AUTHORS" .IX Header "AUTHORS" Eric Blake .PP Richard W.M.
