Getting references

Function: ap_coefft* ap_linexpr0_cstref (ap_linexpr0_t* e)

Get a reference to the constant. Do not free it.

Function: ap_coefft* ap_linexpr0_coeffref (ap_linexpr0_t* e, ap_dim_t dim)

Get a reference to the coefficient associated to the dimension dim in expression e.

Do not free it. In case of sparse representation, possibly induce the addition of a new linear term.

Return NULL if:

• In case of dense representation, dim>=e->size.
• In case of sparse representation, dim==AP_DIM_MAX.
