Most users need not directly employ this routine and the other error handlers, but can instead use the simplified interface SETERRQ, which has the calling sequence

Notes for experienced users

Use PetscPushErrorHandler() to set the desired error handler. The currently available PETSc error handlers include PetscTraceBackErrorHandler(), PetscAttachDebuggerErrorHandler(), PetscAbortErrorHandler(), and PetscMPIAbortErrorHandler()
