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.
