ReadStructFromModeHelper function (usermode_accessors.h)

The ReadStructFromModeHelper function is a helper function that safely reads a structure of a specified size from memory based on the specified processor mode.

Syntax

void ReadStructFromModeHelper(
  VOID            *Destination,
  const VOID      *Source,
  SIZE_T          Size,
  KPROCESSOR_MODE Mode
);

Parameters

Destination

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

Source

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

Size

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

Mode

[in] The processor mode that determines how the memory access is performed.

Return value

None

Remarks

This function is a helper function used internally by the user-mode accessor functions. It provides mode-aware reading of structures from memory, with extra safety checks when accessing user-mode memory.
