The pointer to the function is to use the pointer to save the address of the function as follows:
Void sub (int A, int B); int _ tmain (INT argc, _ tchar * argv []) {void (* t_vp) (int A, int B ); // define the function pointer t_vp = sub; // assign a value to the function pointer (* t_vp) (5, 6); // call the function pointer system ("pause"); Return 0 ;} void sub (int A, int B) {cout
To assign a value to a function pointer, you need to explain the following step: In t_vp = sub, sub is the fu

Multi-threaded collection Security
If a set is used in multiple threads without any security processing, it is very easy to cause system crashes or various errors. In the latest project, a set is changed after socket communication. As a result, the system crashes directly without any errors.
After troubleshooting, it is found that the system exits after a set is executed within a certain period of time. Finally, it is found that a dictionary set is faulty. After thinking a little bit, we thought
