Note: Most of the articles in this classification from the "Deep analysis of the Linux kernel source code" a book, and other reference information such as "Complete analysis of the Linux kernel", "Linux C programming One-stop learning", and so on,

Because different processes are running in their own different memory spaces. The other party is not aware of the modification of the variable. therefore The transfer of information between processes cannot be done directly through variables or

POSIX's shared memory is implemented through the tmpfs file system attached to the user space, while the shared memory of System V is implemented by the tmpfs of the kernel itself, the two are actually implemented using the same mechanism. The
