Annotation of researchv10no/cmd/nupas/ipc/doc, revision 1.1.1.1

1.1       root        1: There are two routines implemented: ipcpath and ipcopen.  Both appear to
                      2: work pretty much the same as the V10 versions.  ipcpath converts
                      3: a destination with default network and service name to a string
                      4: useable by ipcopen.  Ipcopen processes destinations with the
                      5: following format:
                      6: 
                      7:        dialer!destination
                      8: 
                      9: The following networks are supported:
                     10: 
                     11:        dk  - connect through datakit dkdial(2) call.  Host address
                     12:                must be a valid datakit string.
                     13: 
                     14:        tcp - connect through a socket.  Host address is obtained
                     15:                by gethostbyname.  Format of destination is
                     16:                host!service.  If the service name is the form
                     17:                tcp.nn or nn, call service nn.  If it is an alphabetic,
                     18:                obtain the port number through getservbyname.
                     19: 
                     20:        mx - same as tcp, except ask the resolver for MX records
                     21:                and try those addresses.  If no MX records work,
                     22:                try the A address of the host.
                     23: 
                     24:        proxy - connect to the Internet through the gateway proxy
                     25:                service whose
                     26:                address is given in the ipcopen.c source.  The
                     27:                connection may be through datakit or tcp.
                     28: 
                     29:        (others)        some synonyms for various proxy destinations.
                     30: 
                     31: All the code is contained in a directory named `ipc'.  The command
                     32:        make init net1 net2 ... lib
                     33: will install code to call the networks requested from the network names
                     34: given above.  Uninstalled networks will call a stub that aborts
                     35: if the network is tried.
                     36:
