      7:    PetscMPIAbortErrorHandler - Calls MPI_abort() and exits.

      9:    Not Collective

     11:    Input Parameters:
     12: +  comm - communicator over which error occurred
     13: .  line - the line number of the error (indicated by __LINE__)
     14: .  fun - the function where the error occurred (indicated by __FUNCT__)
     15: .  file - the file in which the error was detected (indicated by __FILE__)
     16: .  dir - the directory of the file (indicated by __SDIR__)
     17: .  mess - an error text string, usually just printed to the screen
     18: .  n - the generic error number
     19: .  p - PETSC_ERROR_INITIAL if error just detected, otherwise PETSC_ERROR_REPEAT
     20: -  ctx - error handler context

     24:    Notes:
     25:    Most users need not directly employ this routine and the other error
     26:    handlers, but can instead use the simplified interface SETERRQ, which has
     27:    the calling sequence
     28: $     SETERRQ(comm,n,p,mess)

     30:    Notes for experienced users:
     31:    Use PetscPushErrorHandler() to set the desired error handler.  The
     32:    currently available PETSc error handlers include PetscTraceBackErrorHandler(),
     33:    PetscMPIAbortErrorHandler(), PetscAttachDebuggerErrorHandler(), and PetscAbortErrorHandler().
