1. If each thread executes the same code, the same Runnable object can be used, and the Runnable object has that shared data, for example, the ticket system can do so.2. If t
Shared MemoryShared memory allows two unrelated processes to access the same logical memory. Shared memory is a very efficient way to share and pass data between two running processes. Memory that is shared between different processes is usually scheduled as the same piece of physical memory. Processes can connect the same piece of
Inter-process communication in Linux (5): Shared Memory (2)
The system calls MMAP () to map a common file to implement shared memory. System V maps files in the SHM of a special file system to implement shared memory communication between processes. That is to say, each shared memory area corresponds to a file in the s
, and multiple devices use the same interrupt line number, all the handlers of the same Interrupt Device line number are linked to a linked list. In this way, when the next interrupt is generated by sharing the interrupt line number, the corresponding linked list of the handler will be traversed, however, this interrupt is generated between multiple devices that use the same interrupt line number. It is imp
