Problem in hashtable

[jzijin]

The function hashtable_new_conf in hashtable.c. I found that table->buckets = conf->mem_calloc(table->capacity, sizeof(TableEntry)); It confuse me. The type of table->buckets is TableEntry**. Why do not just use table->buckets = conf->mem_calloc(table->capacity, sizeof(TableEntry*)); I modify table->buckets = conf->mem_calloc(table->capacity, sizeof(TableEntry)); to table->buckets = conf->mem_calloc(table->capacity, sizeof(TableEntry*)); and do test, It also run well!

I think you are correct. When allocating the buckets memory, only the size of a pointer is needed. The memory of the TableEntry struct itself is allocated separately in hashtable_add. The reason it works now is because the allocated memory is more than what is actually needed, but this is wasting too much memory.
