sm_open

Definition: include builtins\ipc.e
atom pSharedMem = sm_open(string name)
Description: Retrieve the address of a block of shared memory, identified by name, that has already been allocated, usually by another application.

Returns: the address of the block of memory identified by name.
If a block of memory that is identified by name does not already exist, then sm_open() returns one of the predefined error values.
Comments: Each application must call sm_close() to close it’s handle to the shared memory.
A block of shared memory will continue to exist until all handles to it have been closed.
