而 writeBytes() 函数首先写入了字符串的长度,在读取文件时,先从前四个字节读出字符串长度,知道数据有多少个字节就可以正确读出了。 QDataStream 提供了与 writeBytes() 对应的函数 readBytes(),它可以自动读取长度和内容,适用于字符串数据的读取。 dat文件格式 用saveBinaryFile() 函数保存数据为标准编码二进制文...
that need to be read from the given file. Finally, the fourth argument to the function is theFILEpointer from which the data should be read. In the following example, we open and write some arbitrary bytes to the file namedinput.txt. Then, we close the file and open it again for ...

My Binary data format is too complex one to be decoded by a JBBP script No problems! JBBP parser works over com.igormaznitsa.jbbp.io.JBBPBitInputStream class which can be used directly and allows read bits, bytes, count bytes and align data. For writing there is similar class JBBPBit...
