删除文件删除不了
我在使用网络接收了临时的数据，但是接收完成后，不能删除这个文件，使用IFILEMGR_GetLastError 得到 EFILEOPEN。但是 我已经释放了，不知道问题出在哪，下面是我的代码。麻烦大侠们看看

}
}
此函数用于删除由给定文件名标识的文件。
int IFILEMGR_Remove
(
IFileMgr * pIFileMgr,
const char * pszName
)
SUCCESS： 如果成功
EFAILED： 如果失败
代码修改为：
FREEIF(buffer);
ISOURCE_Release(pISource);
nRet = IFILE_Release(pIFile);
DBGPRINTF("IFILE_Release:%d",nRet);
nRet = IFILEMGR_Remove(pIFileMgr，DATA_TEMPRECEIVE);
nRet = IFILEMGR_Release(pIFileMgr);
DBGPRINTF("IFILEMGR_Release:%d",nRet);
--------------------编程问答-------------------- 你在哪里调用的remove？ --------------------编程问答-------------------- 重置下文件指针：
IFILE_Seek(pIFile, _SEEK_START, 0);
再去Move --------------------编程问答-------------------- 先要释放掉pIFile指针的，不然删除的文件还是在被使用中
