# sm_close

Definition: | include builtins\ipc.e sm_close(object id)
Description: | This routine releases a handle to a block of shared memory. id: can be either the address returned by sm_create() or sm_open(), or the string-id used to identify the memory.
pwa/p2js: | Not supported
Comments: | Once an application calls sm_close(), that memory is no longer available to that application, but does not mean that the memory is no longer available to other applications. 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.
