最近学逆向 看到一段代码 苦于对结构体不是很熟悉 求分析

signed int __cdecl sub_4011E0()
{
  int v0; // edi@4
  signed int v1; // ecx@4
  bool v2; // zf@6
  signed int v3; // ecx@7
  const void *v4; // esi@7
  CHAR *v5; // edi@7
  unsigned int v6; // edx@7
  signed int v7; // ecx@7
  HANDLE v8; // eax@10
  HANDLE v9; // eax@10
  signed int result; // eax@11
  struct _PROCESS_INFORMATION ProcessInformation; // [sp+8h] [bp-360h]@10
  struct _STARTUPINFOA StartupInfo; // [sp+18h] [bp-350h]@10
  CHAR szLongPath; // [sp+5Ch] [bp-30Ch]@2
  CHAR String2; // [sp+160h] [bp-208h]@4
  CHAR CommandLine; // [sp+264h] [bp-104h]@1

  if ( !GetEnvironmentVariableA("COMSPEC", &CommandLine, 0x104u)
    || !GetModuleFileNameA(0, &szLongPath, 0x104u)
    || !GetShortPathNameA(&szLongPath, &szLongPath, 0x104u) )
    goto LABEL_15;
  Sleep(1u);
  strcpy(&String2, " /C del ");
  lstrcatA(&String2, &szLongPath);
  v0 = (int)" > nul";
  v1 = -1;
  do
  {
    if ( !v1 )
      break;
    v2 = *(_BYTE *)v0++ == 0;
    --v1;
  }
  while ( !v2 );
  v3 = ~v1;
  v4 = (const void *)(v0 - v3);
  v5 = &String2;
  v6 = v3;
  v7 = -1;
  do
  {
    if ( !v7 )
      break;
    v2 = *v5++ == 0;
    --v7;
  }
  while ( !v2 );
  memcpy(v5 - 1, v4, v6);
  lstrcatA(&CommandLine, &String2);
  ProcessInformation.hThread = 0;
  ProcessInformation.dwProcessId = 0;
  memset(&StartupInfo.lpReserved, 0, 0x40u);
  ProcessInformation.hProcess = 0;
  ProcessInformation.dwThreadId = 0;
  StartupInfo.cb = 68;
  StartupInfo.dwFlags = 1;
  StartupInfo.wShowWindow = 0;
  v8 = GetCurrentProcess();
  SetPriorityClass(v8, 0x100u);
  v9 = GetCurrentThread();
  SetThreadPriority(v9, 15);
  if ( CreateProcessA(0, &CommandLine, 0, 0, 0, 0xCu, 0, 0, &StartupInfo, &ProcessInformation) )
  {
    SetPriorityClass(ProcessInformation.hProcess, 0x40u);
    SetThreadPriority(ProcessInformation.hThread, -15);
    ResumeThread(ProcessInformation.hThread);
    result = 1;
  }
  else
  { 
 
LABEL_15:
    result = 0;
  }
  return result;
}

把他翻译成正规可运行的代码 其中LABEL_15不了解什么意思

struct _PROCESS_INFORMATION 这句话C++原型里面应该是PROCESS_INFORMATION 吧
原先我就PROCESS_INFORMATION 用的 为什么他还要用struct呢？
[解决办法]
LABEL_15就是个位置标记,前面有个goto LABEL_15,表示出错了代码跳到这里执行.
相当于汇编里面的
jmp LABEL_15
...
LABEL_15:
...
nop
