packaging the target file into a static library can only be used with the AR command instead of the tar command. The option R indicates that the file list is added to the package, and if the package does not exist, it is created if the package already has a file with the same name replaced by the new one. S is dedicated to generating static libraries, which represent the creation of indexes for static libraries, which are used by the linker. The Ranl

Shared memory allows multiple processes to access the same memory space. It is the fastest available IPC format. It is designed to reduce the running efficiency of other communication mechanisms. It is often used in conjunction with other communication mechanisms, such as semaphores, to achieve synchronization and mutual exclusion between processes. Other processes can "Connect" the s

The shared memory area is a part of the physical memory shared by multiple processes. If multiple processes map the memory area to their virtual address space, these processes can directly access the shared memory area for communication. Shared memory is the
