MIDL_user_allocate (

Routine Description:
Allocates storage for RPC transactions. The RPC stubs will either call
MIDL_user_allocate when it needs to un-marshall data into a buffer
that the user must free. RPC servers will use MIDL_user_allocate to
allocate storage that the RPC server stub will free after marshalling
the data.
Arguments:
NumBytes - The number of bytes to allocate.
Return Value:
none

/*++
Routine Description:
Frees storage used in RPC transactions. The RPC client can call this
function to free buffer space that was allocated by the RPC client
stub when un-marshalling data that is to be returned to the client.
The Client calls MIDL_user_free when it is finished with the data and
desires to free up the storage.
The RPC server stub calls MIDL_user_free when it has completed
marshalling server data that is to be passed back to the client.
Arguments:
MemPointer - This points to the memory block that is to be released.
Return Value:
none.
