IDebugHostMemory::ReadBytes method (dbgmodel.h)

  • Article

Reads a number of bytes from the address space of the target as defined by the inpassed context and location. The number of bytes read is returned in "bytesRead" upon success.

Syntax

HRESULT ReadBytes(
  IDebugHostContext *context,
  Location          location,
  void              *buffer,
  ULONG64           bufferSize,
  ULONG64           *bytesRead
);

Parameters

context

The host context in which to read bytes. This represents, for example, the address space in which the location exists.

location

The location at which to read bytes. This location may represent a virtual address within the address space defined by context or it may represent something like a register within a context record for a thread.

buffer

The bytes read from the debug target will be written to this buffer.

bufferSize

The size of the buffer and the number of bytes to read.

bytesRead

The number of bytes actually read from the debug target will be returned here. If the method can complete a partial read, S_FALSE will be returned and the value in bytesRead may be less than the requested number of bytes. If the method returns S_OK, a full read was completed.

Return value

This method returns HRESULT which indicates success or failure.
