The WriteTypedDataVirtual method writes data to the target's virtual address space. The number of bytes written is the size of the specified type.

Syntax

HRESULT WriteTypedDataVirtual(
  [in]            ULONG64 Offset,
  [in]            ULONG64 Module,
  [in]            ULONG   TypeId,
  [in]            PVOID   Buffer,
  [in]            ULONG   BufferSize,
  [out, optional] PULONG  BytesWritten
);

Parameters

[in] Offset

Specifies the location in the target's virtual address space where the data will be written.

[in] Module

Specifies the base address of the module containing the type.

[in] TypeId

Specifies the type ID of the type.

[in] Buffer

Specifies the buffer containing the data to be written.

[in] BufferSize

Specifies the size in bytes of the buffer Buffer. This is the maximum number of bytes to be written.

[out, optional] BytesWritten

Receives the number of bytes that were written. If BytesWritten is NULL, this information is not returned.

Return value

This method may also return error values. See Return Values for more details.

Return code	Description
S_OK	The method was successful.
S_FALSE	The method was successful. All the bytes in the buffer Buffer were written. However, the buffer was smaller than the size of the type specified.

Remarks

This is a convenience method. The same result can be obtained by calling GetTypeSize and WriteVirtual.
