      5:    PetscMPIAbortErrorHandler - Calls PETSCABORT and exits.

      7:    Not Collective

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

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

     26:    Notes for experienced users:
     27:    Use PetscPushErrorHandler() to set the desired error handler.  The
     28:    currently available PETSc error handlers include PetscTraceBackErrorHandler(),
     29:    PetscMPIAbortErrorHandler(), PetscAttachDebuggerErrorHandler(), and PetscAbortErrorHandler().
