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

1	getNumQConstrsCPLEX(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 getNumQConstrs which calls the CPLEX function CPXgetnumqconstrs.

If successful the number of quadratic constraints is returned. If env or lp do not exist, zero is returned.
