Return value
The function RpcSmFree returns the following value.
| Value | Meaning |
|---|---|
|
The call succeeded. |
Note For a list of valid error codes, see
RPC Return Values.
Remarks
Applications use RpcSmFree to free memory allocated by RpcSmAllocate. In cases where the stub allocates the memory for the application, RpcSmFree can also be used to release memory. For more information, see Memory Management.
To improve performance, the RpcSmFree function only marks memory for release. Memory is not actually released until your application calls the RpcSmDisableAllocate function. To release memory immediately, invoke the midl_user_free function.
Note that the handle of the thread calling RpcSmFree must match the handle of the thread that allocated the memory by calling RpcSmAllocate.. Use RpcSmGetThreadHandle and RpcSmSetThreadHandle to pass handles from thread to thread.
