通过进程PID获取可执行文件路径(QueryFullProcessImageName)

需要用到如下API

BOOL WINAPI QueryFullProcessImageName(
  __in     HANDLE hProcess,
  __in     DWORD dwFlags,
  __out    LPTSTR lpExeName,
  __inout  PDWORD lpdwSize
);

32位的程序调用此API同样能获取到64位进程的可执行文件路径。

下面是微软在文档中的说明，由于该API很简单就不再复述了

hProcess [in]

A handle to the process. This handle must be created with the PROCESS_QUERY_INFORMATION or PROCESS_QUERY_LIMITED_INFORMATION access right. For more information, see Process Security and Access Rights 
.

dwFlags [in]

This parameter can be one of the following values.

Value	Meaning
0	The name should use the Win32 path format.
PROCESS_NAME_NATIVE 0x00000001	The name should use the native system path format.
