如果为这些不受支持的服务之一调用 Seek,它将传回 Win32 错误代码 ERROR_INTERNET_INVALID_OPERATION。打开文件时,文件指针位于偏移量 0 处,即文件的开头。备注 使用Seek 可能会致使隐式调用 Flush。示例请参阅基类实现示例 (CFile::Seek)。CInternetFile::SetReadBufferSize...
strcpy、strcat这类函数不安全,因为它们在复制字符串时不检查目标缓冲区的大小,可能会导致缓冲区溢出。 而strncpy、strncat、strncmp这类函数相对来说更安全,因为它们在复制/追加字符串时会限定最大长度参数n,避免无限制地写入目标缓冲区。 点击—>手把手教你配置VS的常见函数如何不报错!
