In C and C ++ languages, a shared space called a heap is provided. During the program running, the system uses the functions malloc () and free () dynamically apply for or release a continuous space.In C and C ++, pointers can be used to access and

PrefaceMutex lock is used to ensure that only a single thread or process has mutex access to shared resources at any time. Here, the mutex in posix thread, the mutex in win32, and the critical section are used, they are collectively referred to as

The hard disk serial number (serial number) is not equal to the volume name. Although the latter is easy to obtain, it will be overwritten after formatting the partition, which is unreliable. Unfortunately, many friends often cannot tell this point.
