tokyocabinet 列表中的内存泄漏

Question

Do I to use the function free() after the use:

TCLIST *list = tcbdbrange();

or using enough :

tclistdel(list); 

Do I to free(p) for: p = (lk_key*) tclistval(list,...) or tclistdel(list) delete all elemenst of list ?

Answer 1

Haven't you read any documentation ? These are typical questions that should be answered by the docs. As a matter of fact, they are:

Because the object of the return value is created with the function ' tclistnew ', it should be deleted with the function ' tclistdel ' when it is no longer in use.

I interpret that to mean that you don't have to iterate over the list and delete each element individually.
