midl_user_free attribute

The midl_user_free function is provided by client and server applications to deallocate dynamically allocated memory.


void __RPC_API midl_user_free(void __RPC_FAR * p);

Parameters

p

A pointer to the memory block to be freed.

Remarks

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 objects referenced by pointers:

  • The server application should call midl_user_free to free memory allocated by the application—for example, when deleting a specified node.
  • The server stub calls midl_user_free to release memory on the server after marshaling all [out] arguments, [in, out] arguments, and the return value.

Examples


#include <windows.h>

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