Low level interface function to the IBM ILOG CPLEX function CPXgetnumquad. Consult the IBM ILOG CPLEX documentation for more detailed information.

1	getNumQuadCPLEX(env, lp)

`env`	An object of class `"cplexPtr"` as returned by `openEnvCPLEX`. This is basically a pointer to an IBM ILOG CPLEX environment.
`lp`	An object of class `"cplexPtr"` as returned by `initProbCPLEX`. This is basically a pointer to an IBM ILOG CPLEX problem object.

Interface to the C function getNumQuad which calls the CPLEX function CPXgetnumquad.

If successful the number of variables that have quadratic objective coefficients is returned. If env or lp do not exist, zero is returned.
