请问API函数createthread怎么使用啊

C 代码复制

#include <windows.h>
#include <stdio.h>
int __stdcall hi(int i) {
        Sleep(i * 80);
        printf("hi %d\n", i);
        return 0;
}
 
int main() {
        for (int i = 0; i < 10; i++) {
                CloseHandle(CreateThread(0, 0, (LPTHREAD_START_ROUTINE)hi, i, 0, 0));
        }
        Sleep(1000);
        getchar();
        return 0;
}

#include <windows.h>


#include <stdio.h>


int __stdcall hi(int i) {


        Sleep(i * 80);


        printf("hi %d\n", i);


        return 0;


}


 


int main() {


        for (int i = 0; i < 10; i++) {


                CloseHandle(CreateThread(0, 0, (LPTHREAD_START_ROUTINE)hi, i, 0, 0));


        }


        Sleep(1000);


        getchar();


        return 0;


}

感觉已经忘记怎么写代码了..

那要是用ruby代码写呢

RUBY 代码复制

u = Win32API.new("kernel32", "GetModuleHandleA", "p", "l").call("user32")
m = Win32API.new("kernel32", "GetProcAddress", "lp", "l").call(u, "MessageBoxA")
func = [0x8B, 0x4C, 0x24, 0x04, 
        0x31, 0xC0, 0x50, 0x50, 0x51, 0x50, 0xB8].pack("C*") +
       [m].pack("l") +
       [0xFF, 0xD0, 0xC2, 0x04, 0x00].pack("C*")
=begin
  mov ecx, [esp+4] 参数 i.to_s
  xor eax,eax
  push eax
  push eax
  push ecx
  push eax
  mov eax,MessageBoxA
  call eax  0,text,0,0
  ret 4
=end
c = Win32API.new("kernel32", "CreateThread", "llppll", "v")
for i in 0...5
  c.call(0, 0, func, i.to_s, 0, 0)
end
loop{Graphics.update}

u = Win32API.new("kernel32", "GetModuleHandleA", "p", "l").call("user32")


m = Win32API.new("kernel32", "GetProcAddress", "lp", "l").call(u, "MessageBoxA")


func = [0x8B, 0x4C, 0x24, 0x04, 


        0x31, 0xC0, 0x50, 0x50, 0x51, 0x50, 0xB8].pack("C*") +


       [m].pack("l") +


       [0xFF, 0xD0, 0xC2, 0x04, 0x00].pack("C*")


=begin


  mov ecx, [esp+4] 参数 i.to_s


  xor eax,eax


  push eax


  push eax


  push ecx


  push eax


  mov eax,MessageBoxA


  call eax  0,text,0,0


  ret 4


=end


c = Win32API.new("kernel32", "CreateThread", "llppll", "v")


for i in 0...5


  c.call(0, 0, func, i.to_s, 0, 0)


end


loop{Graphics.update}

道理还是一样的
但是新线程的函数不能是ruby函数 因为机制不一样
得先编译好
汇编毕竟麻烦
