What types of sockets are available in VxWorks?

Question

Vxworks supports standard IP v4 and IP v6 sockets, but sockets are also used for other purposes.
What other types of sockets are available?

Answer 1

The socket types you can use depend on the communication domain you create your socket in. The listed socket types are:

SOCK_DGRAM      unreliable  not sequenced  possibly duplicated  message
SOCK_STREAM     reliable      sequenced       non-duplicated    stream
SOCK_SEQPACKET  reliable      sequenced       non-duplicated    message
SOCK_RDM        reliable    not sequenced  possibly duplicated  message

SOCK_RAW        protocol/interface dependent, access to internal protocol info

VxWorks also defines the following communication domains:

AF_INET     IPv4
AF_INT6     IPv6
AF_ROUTE    routing
AF_LOCAL    local Inter-process Communications
AF_TIPC     Transparent Inter-Process Communications
AF_MOBILITY Mobile IPv6 

Here is the list of the various sockets supported for the various domains:

AF_INET     SOCK_DGRAM, SOCK_STREAM, SOCK_RAW
AF_INT6     SOCK_DGRAM, SOCK_STREAM, SOCK_RAW
AF_ROUTE    SOCK_RAW
AF_LOCAL    SOCK_SEQPACKET
AF_TIPC     SOCK_SEQPACKET, SOCK_RDM, SOCK_DGRAM, SOCK_STREAM
AF_MOBILITY don't know
