WARNINGS

Programs using a memory window can access shared memory objects created by other programs using the

same window (depending upon permissions). However, by default, programs using a memory window

may not be able to access shared memory objects created by programs using other windows or those not

using windows at all.

To enable access to a shared memory object across programs using different windows, or between those

using windows and those not using windows, the program must specify special options when creating the

object. See shmget(2) and mmap(2) for details.
