In other cases, the restriction may be due to the implementation, or may be imposed by the underlying platform for example, QTcpSocket does not support Unbuffered mode, and limitations in the native API prevent QFile from supporting Unbuffered on Windows. Some of these restrictions are implied by the type of device that is represented by a subclass. (since Qt 5.11)Ĭertain flags, such as Unbuffered and Truncate, are meaningless when used with some subclasses. Other classes might use this flag in the future, but until then using this flag with any classes other than QFile may result in undefined behavior. Note that using this flag with ReadOnly alone is redundant, as ReadOnly already fails when the file does not exist. This flag must be specified alongside ReadOnly, WriteOnly, or ReadWrite.
