What XTI can do

XTI allows a process to perform a variety of functions associated with network communication. All of these functions operate on a ``transport endpoint.'' A transport endpoint is a link between a transport provider and the process that wants to communicate over the network using that provider.
The transport endpoint is always identified by a file descriptor (an integer index into the system file descriptor table).

Specifically, a process can call XTI functions (listed in parentheses) to

• create a transport endpoint
  (t_open)

• associate a suitable address with
  the transport endpoint (t_bind)

• request to connect to another
  process (t_connect)

• listen for a connection request from
  another process (t_listen)

• accept another process's request
  to connect (t_accept)

• reject another process's attempt
  to connect (t_snddis)

• send data to a process
  (t_snd or t_sndudata)

• receive data from a process
  
  (t_rcv or t_rcvudata)

• disassociate an address from the
  transport endpoint (t_unbind)

• detect error conditions raised by the
  transport provider (t_look)

• negotiate various options available from
  the transport provider (t_optmgmt)

• request to end a connection with
  another process (t_snddis)

• await a request from another process
  to end the connection (t_rcvdis)

• delete a transport endpoint
  (t_close)

• get the current state of the transport provider
  (t_getstate)

• get current information about the transport provider
  (t_getinfo)
