midl_user_free

void __RPC_USER midl_user_free(void __RPC_FAR * pBuffer);

Parameters

pBuffer

Specifies a pointer to the memory that is to be freed.

Both client application and server application must implement the midl_user_free function, unless you are compiling in OSF-compatibility (/osf) mode. The midl_user_free function must be able to free all storage allocated by midl_user_allocate.

Applications and stubs call midl_user_free when dealing with allocated objects. For example:

• The server application should call midl_user_free to free memory allocated by the application, such as when deleting a pointed-at node.
• The server stub calls midl_user_free to release memory on the server after marshalling all out arguments, in, out arguments, and the function return value.

For example, the RPC Win32 sample program that displays "Hello, world" implements midl_user_free in terms of the C function free:

void __RPC_USER midl_user_free(void __RPC_FAR * p)
{
    free(p);
}
 

Note  If the Rpcss package is enabled (for example, as the result of using the enable_allocate attribute), RpcSmFree can be used to free memory. See Rpcss Memory Management Model for more information.
