* -----------------------------------------------------------------
* Function : CVSpbcg
* -----------------------------------------------------------------
* A call to the CVSpbcg function links the main CVODE integrator
* with the CVSPBCG linear solver.
*
* cvode_mem is the pointer to the integrator memory returned by
* CVodeCreate.
*
* pretype is the type of user preconditioning to be done.
* This must be one of the four enumeration constants
* PREC_NONE, PREC_LEFT, PREC_RIGHT, or PREC_BOTH defined
* in iterative.h. These correspond to no preconditioning,
* left preconditioning only, right preconditioning
* only, and both left and right preconditioning,
* respectively.
*
* maxl is the maximum Krylov dimension. This is an
* optional input to the CVSPBCG solver. Pass 0 to
* use the default value CVSPBCG_MAXL=5.
*
* The return value of CVSpbcg is one of:
* CVSPILS_SUCCESS if successful
* CVSPILS_MEM_NULL if the cvode memory was NULL
* CVSPILS_MEM_FAIL if there was a memory allocation failure
* CVSPILS_ILL_INPUT if a required vector operation is missing
* The above constants are defined in cvode_spils.h
