# 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.
pwa/p2js: | Not supported
Comments: | Each application must call sm_close() to close its handle to the shared memory. A block of shared memory will continue to exist until all handles to it have been closed.
