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.
