* xprt = svcunix_create(sock, send_buf_size, recv_buf_size);
|
166 |
|
|
*
|
167 |
|
|
* Creates, registers, and returns a (rpc) unix based transporter.
|
168 |
|
|
* Once *xprt is initialized, it is registered as a transporter
|
169 |
|
|
* see (svc.h, xprt_register). This routine returns
|
170 |
|
|
* a NULL if a problem occurred.
|
171 |
|
|
*
|
172 |
|
|
* If sock<0 then a socket is created, else sock is used.
|
173 |
|
|
* If the socket, sock is not bound to a port then svcunix_create
|
174 |
|
|
* binds it to an arbitrary port. The routine then starts a unix
|
175 |
|
|
* listener on the socket's associated port. In any (successful) case,
|
176 |
|
|
* xprt->xp_sock is the registered socket number and xprt->xp_port is the
|
177 |
|
|
* associated port number.
|
178 |
|
|
*
|
179 |
|
|
* Since unix streams do buffered io similar to stdio, the caller can specify
|
180 |
|
|
* how big the send and receive buffers are via the second and third parms;
|
181 |
|
|
* 0 => use the system default.
