libdaemon0 0.12-0.1 (amd64 binary) in ubuntu gutsy

 libdaemon is a leightweight C library which eases the writing of UNIX
 daemons. It consists of the following parts:
  * A wrapper around fork() which does the correct daemonization
    procedure of a process
  * A wrapper around syslog() for simpler and compatible log output to
    Syslog or STDERR
  * An API for writing PID files
  * An API for serializing UNIX signals into a pipe for usage with
    select() or poll()
 .
 Routines like these are included in most of the daemon software
 available. It is not that simple to get it done right and code
 duplication cannot be a goal.
 .
 This package includes the run time library.
