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

        SETERRQ(number,p,mess)

### Notes for experienced users

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