Report Typos and Errors

  2:  #include <petscsys.h>

  4: /*@C
  5:    PetscMPIAbortErrorHandler - Calls MPI_abort() 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

 18:    Level: developer

 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().
