error: expected declaration specifiers or '. . .' before '*' token

(python)最近要用到CreateRemoteThread,找不到LPTHREAD_START_ROUTINE于是自己定义一个.

typedef DWORD (__stdcall *LPTHREAD_START_ROUTINE) (LPVOID lpThreadParameter);

结果显示

lsr.c:1:26: error: expected declaration specifiers or '...' before '*' token
 typedef DWORD (__stdcall *LPTHREAD_START_ROUTINE) (LPVOID lpThreadParameter);
                          ^

为什么?

PS:还可能会有
unknown type name 'DWORD'
unknown type name 'LPVOID'

Using built-in specs.
