DMTSGetRHSFunction

get TS explicit residual evaluation function

#include "petscts.h" 
PetscErrorCode DMTSGetRHSFunction(DM dm,TSRHSFunction *func,void **ctx)

Not Collective

dm -DM to be used with TS

	func	- residual evaluation function, see TSSetRHSFunction() for calling sequence
	ctx	- context for residual evaluation

TSGetFunction() is normally used, but it calls this function internally because the user context is actually associated with the DM.
