  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: .  mess - an error text string, usually just printed to the screen
 17: .  n - the generic error number
 18: .  p - PETSC_ERROR_INITIAL if error just detected, otherwise PETSC_ERROR_REPEAT
 19: -  ctx - error handler context

 21:    Level: developer

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

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

 34:    Concepts: error handler^stopping
