Further information
1. XPRScreateprob must be called after XPRSinit and before using the other Optimizer routines.
2. Any number of problems may be created in this way, depending on your license details. All problems should be removed using XPRSdestroyprob once you have finished working with them.
3. If XPRScreateprob cannot complete successfully, a nonzero value is returned and *p_prob is set to NULL (as a consequence, it is not possible to retrieve further error information using e.g. XPRSgetlasterror).
