PWINDBG_WRITE_PROCESS_MEMORY_ROUTINE function

The PWINDBG_WRITE_PROCESS_MEMORY_ROUTINE (WriteMemory) function works like the Win32 WriteProcessMemory routine. It writes memory to the process being debugged. The entire area to be written must be accessible, or the operation fails.

Syntax

ULONG  WriteMemory(
   ULONG_PTR offset,
   LPCVOID   lpbuffer,
   ULONG     cb,
   PULONG    lpcbBytesWritten
);

Parameters

  • offset
    Specifies the base address of the memory to be written in the process that is being debugged.

  • lpbuffer
    Points to the buffer that contains the data to be written.

  • cb
    Specifies the number of bytes that WriteMemory should write.

  • lpcbBytesWritten
    Receives the actual number of bytes that WriteMemory transferred from 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

For a WdbgExts extension, include wdbgexts.h. For a DbgEng extension, include wdbgexts.h before dbgeng.h. See Writing DbgEng Extension Code for details.
