PWINDBG_READ_PROCESS_MEMORY_ROUTINE callback function (wdbgexts.h)

  • Article

The PWINDBG_READ_PROCESS_MEMORY_ROUTINE (ReadMemory) function works like the Win32 ReadProcessMemory function. It reads memory from the process being debugged. The entire area to be read must be accessible, or the operation fails.

Syntax

PWINDBG_READ_PROCESS_MEMORY_ROUTINE PwindbgReadProcessMemoryRoutine;

ULONG PwindbgReadProcessMemoryRoutine(
  ULONG_PTR offset,
  PVOID lpBuffer,
  ULONG cb,
  PULONG lpcbBytesRead
)
{...}

Parameters

offset

Specifies the base address of the memory to be read in the process that is being debugged.

lpBuffer

Points to the buffer to receive the memory read.

cb

Specifies the number of bytes that you want ReadMemory to read.

lpcbBytesRead

Receives the actual number of bytes that ReadMemory transferred into the buffer. This parameter is optional; if it is NULL, it is ignored.

Return value

If the routine succeeds, the return value is TRUE; otherwise, it is FALSE.

Remarks

If you are writing a WdbgExts extension, include wdbgexts.h. If you are writing a DbgEng extension that calls this function, include wdbgexts.h before dbgeng.h (see Writing DbgEng Extension Code for details).
