◆ SCIPhashsetCreate()
SCIP_RETCODE SCIPhashsetCreate | ( | SCIP_HASHSET ** | hashset, |
BMS_BLKMEM * | blkmem, | ||
int | size | ||
) |
creates a hash set of pointers
- Parameters
-
hashset pointer to store the created hash set blkmem block memory used to store hash set entries size initial size of the hash set; it is guaranteed that the set is not resized if at most that many elements are inserted
