The vlink and tlink programs, compiled from vlink.c and
tlink.c, are small
C programs which contact and interface to a running
MiniVend daemon. The vlink executable is normally made setuid to the user
account which runs MiniVend, so that the UNIX-domain socket file can be set
to secure permissions (user read-write only). It is normally not necessary
for the user to do anything -- they will be compiled by the configuration
program. If the MiniVend daemon is not running, either will display a
message indicating that the server is not available. The following defines
in the produced config.h should be set:
- LINK_FILE
-
Set this to the name of the socket file that will be used for
configuration, usually ``/usr/local/lib/minivend/etc/socket'' or the
``etc/socket'' under the directory you chose for the VendRoot.
- LINK_HOST
-
Set this to the
IP number of the host which should be contacted. The
default of 127.0.0.1 (the local machine) is probably best for many
installations.
- LINK_PORT
-
Set this to the
TCP port number that the MiniVend server will monitor. The default is 7786 (the
ASCII codes for
'M' and
'V') and does not normally need to be changed.
- LINK_TIMEOUT
-
Set this to the number of seconds vlink or tlink should wait before
announcing that the MiniVend server is not running. The default of 45 is
probably a reasonable value.
