Beginner ctypes: Open process and return related information

Directly on the code:

1.

my_debugger_defines.py

Define related structures (parameters are available when creating processes and returning information later)

2, my_debugger.py

Defines a function that creates and tracks a process:

To try, call the function:

1 Import My_debugger 2 3 debugger=my_debugger.debugger ()45 debugger.load ("C:\Windows\ System32\calc.exe")

Problem:

#结构体之间的赋值是如何进行的? By order?
#这里自己定义的process_information结构体跟
Do #win32函数中creatprocess中process_information的成员数量 and locations have to be the same?

#好像也不是这样, because I process_information is consistent, the success of the communication, and I startupinfo inconsistent, also succeeded.
