ipc_ status
return status. See DQP_solve for details
ipc_ alloc_status

char bad_alloc[81]
the name of the array for which an allocation/deallocation error occurred
ipc_ iter
the total number of iterations required
ipc_ cg_iter
the total number of iterations required
ipc_ factorization_status
the return status from the factorization
int64_t factorization_integer
the total integer workspace required for the factorization
int64_t factorization_real
the total real workspace required for the factorization
ipc_ nfacts
the total number of factorizations performed
ipc_ threads
