<A NAME="SNESLineSearchGetSNES"><H1>SNESLineSearchGetSNES</H1></A>
Gets the <A HREF="../SNES/SNES.html#SNES">SNES</A> instance associated with the line search. Having an associated <A HREF="../SNES/SNES.html#SNES">SNES</A> is necessary because most line search implementations must be able to evaluate the function using <A HREF="../SNES/SNESComputeFunction.html#SNESComputeFunction">SNESComputeFunction</A>() for the associated <A HREF="../SNES/SNES.html#SNES">SNES</A>. This routine is used in the line search implementations when one must get this associated <A HREF="../SNES/SNES.html#SNES">SNES</A> instance.
