NAME

       libminicoredumper  -  a  library  for  registering  application  data for dumping with the
       minicoredumper(1)

DESCRIPTION

       libminicoredumper provides an interface for registering binary and text data  for  dumping
       with  the  minicoredumper(1).   The  data  can be dumped into a core(5) file (in case this
       application crashes), or into separate files for simple access.

       If any data is registered for dumping, an anonymous UNIX domain socket is used to  send  a
       message minicoredumper_regd(1), registering this application with minicoredumper(1).  When
       some              other               application               crashes,               the
       minicoredumper(1)willdumptheregistereddatafromthisapplication as well. This feature allows
       variable information from multiple applications to be dumped soon  after  any  application
       crashes.  To  minimize  the  time  between  an  application crash and the dumping of other
       registered applications, the minicoredumper(1) uses PTRACE_SEIZE and  PTRACE_INTERRUPT  to
       temporarily pause registered applications until all dumping is complete.
