SETERRQ4

Macro that is called when an error has been detected,

#include <petscsys.h>
PetscErrorCode SETERRQ4(MPI_Comm comm,PetscErrorCode ierr,char *formatmessage,arg1,arg2,arg3)

Collective on MPI_Comm

	comm	- A communicator, so that the error can be collective
	ierr	- nonzero error code, see the list of standard error codes in include/petscerror.h
	message	- error message in the printf format
	arg1	- argument (for example an integer, string or double)
	arg2	- argument (for example an integer, string or double)
	arg3	- argument (for example an integer, string or double)
	arg4	- argument (for example an integer, string or double)

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

There are also versions for 4, 5, 6 and 7 arguments.

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