Shared memory in Linux can be achieved by following these steps:<\/p>\n

    \n
  1. Create a shared memory segment: Use the shmget system call to create a shared memory segment, specifying parameters such as size and permissions.<\/li>\n
  2. Connect the shared memory segment to the address space of the current process: Use the shmat system call to connect the shared memory segment to the address space of the current process, which returns a pointer to the shared memory segment.<\/li>\n
  3. Using shared memory: accessing and manipulating shared memory segments directly through pointers enables data sharing between processes.<\/li>\n
  4. Disconnect shared memory connection: Use the shmdt system call to disconnect the connection between the current process and the shared memory segment.<\/li>\n
  5. Delete a shared memory segment: Use the shmctl system call to delete the shared memory segment and release resources.<\/li>\n<\/ol>\n

    It is important to note that shared memory is a low-level inter-process communication method where programmers need to manage memory allocation and release on their own. Additionally, they must pay attention to synchronization and mutual exclusion between processes to avoid data inconsistency or race conditions.<\/p>\n","protected":false},"excerpt":{"rendered":"
