This commit (temporarily) leaves MINIX 3 without a TCP/IP service. Thanks go out to Philip Homburg for providing this TCP/IP stack in the first place. It has served MINIX well for a long time. Change-Id: I0e3eb6fe64204081e4e3c2b9d6e6bd642f121973

.SH DESCRIPTION
|
|
socket() creates a socket in the specified \fIdomain\fP. A socket
|
|
is a communications endpoint. Currently two values are supported
|
|
for \fIdomain\fP, PF_INET for internet sockets and PF_UNIX for
|
|
local unix domain sockets. The \fItype\fP of socket can be
|
|
SOCK_STREAM for TCP sockets in the PF_INET \fIdomain\fP or
|
|
SOCK_DGRAM for UDP sockets in the PF_INET \fIdomain\fP. For
|
|
sockets in the PF_UNIX \fIdomain\fP, SOCK_STREAM, SOCK_DGRAM, and
|
|
SOCK_SEQPACKET are supported values for \fItype\fP. The value
|
|
of \fIprotocol\fP is always 0 or IPPROTO_TCP for TCP sockets or
|
|
IPPROTO_UDP for UDP sockets.
|
|
.SH RETURN VALUES
|
|
On success, this function returns a numeric socket descriptor.
|
|
On error, -1 is returned and \fIerrno\fP is set.
|
|
