Description

The WriteStructToUserHelper function is a helper function that safely writes a structure of a specified size to user-mode memory.

Parameters

`Destination`

[out] A pointer to the user-mode memory location where the data will be written.

`Source`

[in] A pointer to the data to write to the destination memory location.
