Here would like to ask the following, func3 - a non-class function function of tt - & gt; B do you have any question, or point to the application in func1 memory?

Which bosses can analyze, a little dizzy,

CodePudding user response:

Func1 ((void *) & amp; Siztof t, t); Mistake, should be you want func2 ((void *) & amp; Siztof t, t);
Test_t tt=args (test_t *); Mistake, should be you want test_t * tt=(test_t * args);

S=in func2 calloc (1, len); Should already be a new memory
