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.
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 it’s handle to the shared memory.
A block of shared memory will continue to exist until all handles to it have been closed.
