Apart from issuing a descriptive error message, dicod
attempts to indicate the reason of its termination by its error code.
As usual, a zero exit code indicates normal termination. The table
below summarizes all possible error codes. For each error code, it
indicates its decimal value and its symbolic name from
include/sysexits.h (if available).
Program terminated correctly.
Only child instances of dicod exit with this code. It
indicates that the child did not receive any ‘DICT’ command
within the time out interval (see inactivity-timeout).
The program was invoked incorrectly, e.g. an invalid option was given, or an erroneous argument was supplied to an option.
Dicod cannot switch to the privileges of the user it is
configured to run as (see user statement).
The server exited due to some error not otherwise described in this table.
Some internal software error occurred.
Some system error occurred, e.g. the program ran out of memory, or file descriptors, or ‘fork’ failed, etc.
An error in the configuration file was detected.
