请教怎样根据process name或者process ID来获得该process的memory address?

[dabaorob]

在MSDN中读取进程memory的方法如下：

BOOL ReadProcessMemory(
HANDLE hProcess,
LPCVOID lpBaseAddress,
LPVOID lpBuffer,
SIZE_T nSize,
SIZE_T* lpNumberOfBytesRead
);

Parameters
hProcess
[in] Handle to the process whose memory is being read. The handle must have PROCESS_VM_READ access to the process.
lpBaseAddress
[in] Pointer to the base address in the specified process from which to read. Before any data transfer occurs, the system verifies that all data in the base address and memory of the specified size is accessible for read access. If this is the case, the function proceeds; otherwise, the function fails.
lpBuffer
[out] Pointer to a buffer that receives the contents from the address space of the specified process.
nSize
[in] Number of bytes to be read from the specified process.
lpNumberOfBytesRead
[out] Pointer to a variable that receives the number of bytes transferred into the specified buffer.

可是我怎样才能获得第二个参数，也就是该进程的base address呢？或者说还有什么别的function能根据process name或者process ID来获得该process的memory address? 翘首以盼哪位大大能给帮忙解答。 多谢多谢。
