Shared memory can best be described as the mapping of an area (segment) of memory
|
|
that will be mapped and shared by more than one process. This is by far the fastest
|
|
form of IPC, because there is no intermediation (i.e. a pipe, a message queue, etc).
|
|
Instead, information is mapped directly from a memory segment, and into the addressing space
|
|
of the calling process. A segment can be created by one process, and subsequently written to and
|
|
read from by any number of processes.
