ReadStructFromUserHelper function (usermode_accessors.h)

The ReadStructFromUserHelper function is a helper function that safely reads a structure of a specified size from user-mode memory.

Syntax

void ReadStructFromUserHelper(
  VOID                *Destination,
  const volatile VOID *Source,
  SIZE_T              Size
);

Parameters

Destination

[out] A pointer to the buffer that receives the data read from user-mode memory.

Source

[in] A pointer to the user-mode memory location from which to read the data.

Size

[in] The size, in bytes, of the data to read.
