readproctitle - maintains an automatically rotated log in memory for inspection by ps(1).

L consists of any number of arguments.  D is one argument consisting of at least five dots.

       readproctitle reads data into the end of D, shifting D to the left to make room. This means that the most
       recent data is visible to process-listing tools such as ps(1).  readproctitle always leaves three dots at
       the left of D.

       For example, if

        readproctitle io errors: ....................

       reads the data

        fatal error xyz
        warning abc

       then its command-line arguments change to

        readproctitle io errors: ... xyz!warning abc!

       with  a  newline character in place of each !. Process-listing tools typically show the newline character
       as ? or \n.

       readproctitle exits when it reaches the end of input.

       Beware that most implementations of ps(1) have small argument-length limits. These limits  apply  to  the
       total length of readproctitleLD.  I have not seen a system with a limit below 512 bytes.

       readproctitle is available in daemontools 0.75 and above.
