`
`process no data if flow control does not allow the smaller of the send low water mark value or
`the entire request to be processed. A select( ) operation testing the ability to write to a socket shall
`return true only if the send low water mark could be processed. The default value for
`SO_SNDLOWAT is implementation-defined and protocol-specific. It is implementation-defined
`whether the SO_SNDLOWAT option can be set.
`The SO_SNDTIMEO option is an option to set a timeout value for the amount of time that an
`output function shall block because flow control prevents data from being sent. As noted in
`Table 2-2 (on page 64), the option value is a timeval structure with the number of seconds and
`microseconds specifying the limit on how long to wait for an output operation to complete. If a
`send operation has blocked for this much time, it shall return with a partial count or errno set to
`[EWOULDBLOCK] if no data were sent. The default for this option is the value zero, which
`indicates that a send operation will not time out. It is implementation-defined whether the
`SO_SNDTIMEO option can be set.
`The SO_TYPE option is used only on getsockopt( ). When this option is specified, getsockopt( )
`shall return the type of the socket (for example, SOCK_STREAM). This option is useful to
`servers that inherit sockets on start-up. SO_TYPE has no default value.
`
`2701 2.10.17 Use of Sockets for Local UNIX Connections
`Support for UNIX domain sockets is mandatory.
`UNIX domain sockets provide process-to-process communication in a single system.

`
`2704 2.10.17.1 Headers
`The symbolic constant AF_UNIX defined in the <sys/socket.h> header is used to identify the
`UNIX domain address family. The <sys/un.h> header contains other definitions used in
`connection with UNIX domain sockets. See the Base Definitions volume of IEEE Std 1003.1-2001,
`Chapter 13, Headers.
`The sockaddr_storage structure defined in <sys/socket.h> shall be large enough to
`accommodate a sockaddr_un structure (see the <sys/un.h> header defined in the Base
`Definitions volume of IEEE Std 1003.1-2001, Chapter 13, Headers) and shall be aligned at an
`appropriate boundary so that pointers to it can be cast as pointers to sockaddr_un structures
`and used to access the fields of those structures without alignment problems. When a
`sockaddr_storage structure is cast as a sockaddr_un structure, the ss_family field maps onto the
`sun_family field.

`
`2716 2.10.18 Use of Sockets over Internet Protocols
`When a socket is created in the Internet family with a protocol value of zero, the implementation
`shall use the protocol listed below for the type of socket created.
`SOCK_STREAM
`IPPROTO_TCP.
`SOCK_DGRAM
`IPPROTO_UDP.
`SOCK_RAW
`IPPROTO_RAW.
`SOCK_SEQPACKET Unspecified.
`A raw interface to IP is available by creating an Internet socket of type SOCK_RAW. The default
`protocol
`for
`type SOCK_RAW shall be identified in the IP header with the value
`IPPROTO_RAW. Applications should not use the default protocol when creating a socket with
`type SOCK_RAW, but should identify a specific protocol by value. The ICMP control protocol is
`accessible from a raw socket by specifying a value of IPPROTO_ICMP for protocol.
