SVC_IO_GetReadPointer

Returns the pointer to the input buffer and its size. If the buffer is internally scattered or chunked in any other way, the pointer and the size relate to the current chunk only. The user can then directly access the buffer via the pointer, but only within the limits of the returned size.
