[BREW函数共享]如何删除目录？

PHP源码:

static void RmDirRecursive(DemoApplet* app,const char* name)
{
  IShell*  shell = app->a.m_pIShell;
  IFileMgr*  filemgr;
  FileInfo  info;

  ISHELL_CreateInstance(shell,AEECLSID_FILEMGR,(void*)&filemgr);

  IFILEMGR_EnumInit(filemgr,name,TRUE);

  while (IFILEMGR_EnumNext(filemgr,&info)) 
{
     RmDirRecursive(app,info.szName);
  }

  IFILEMGR_EnumInit(filemgr,name,FALSE);

  while (IFILEMGR_EnumNext(filemgr,&info)) 
{
    IFILEMGR_Remove(filemgr,info.szName);
 }

  IFILEMGR_RmDir(filemgr,name);

  IFILEMGR_Release(filemgr);
  return;
}

RmDirRecursive(app,"target_dir");
