SETERRQ

Macro to be called when an error has been detected,

#include <petscsys.h>
PetscErrorCode SETERRQ(MPI_Comm comm,PetscErrorCode ierr,char *message)

Collective

	comm	- A communicator, use PETSC_COMM_SELF unless you know all ranks of another communicator will detect the error
	ierr	- nonzero error code, see the list of standard error codes in include/petscerror.h
	message	- error message

Once the error handler is called the calling function is then returned from with the given error code.

See SETERRQ1(), SETERRQ2(), SETERRQ3() for versions that take arguments

Experienced users can set the error handler with PetscPushErrorHandler().

SETERRQ() may be called from Fortran subroutines but SETERRA() must be called from the Fortran main program.
