Description
Sets shared memory value.MBS Plugin provides SharedMemory functions to store UTF-8 text in shared memory, so one process can set it and other can read it, e.g. two versions of FileMaker Pro or two server processes.
The value is lost when computer restarts, but stays when application quits.
On Windows the shared memory objects can't be accessed from another login session. To create a truly global one, we would need to run FileMaker as administrator and prefix the name with "Global\".
Examples
Store text in shared memory:
MBS( "SharedMemory.SetValue"; "test"; "Hello World" )
