PWINDBG_READ_PROCESS_MEMORY_ROUTINE function

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

ULONG  ReadMemory(
   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).

Requirements

Target platform

Desktop

Header

Wdbgexts.h (include Wdbgexts.h or Dbgeng.h)

Library
