问题描述
目前我有一个程序可以将二进制数据加载到字符串流中,然后将数据传递到 fstream,如下所示:
Currently i have a program that loads binary data into a stringstream and then pases the data to a fstream like so:
stringstream ss(stringstream::binary | stringstream::in | stringstream::out);
ss.write(data, 512); // Loads data into stream
// Uses a memory block to pass the data between the streams
char* memBlock = new char[512];
ss.read(memBlock, 512);
ofstream fout("someFile.bin", ios::binary);
fout.write(memBlock, 512); // Writes the data to a file
fout.close();
delete[] memBlock;
我的问题是:有没有更好的方法在流之间传递二进制数据?
My question is: is there a better way to pass the binary data between the streams?
推荐答案
使用streambuf
成员,这就是它们的用途:
Use the streambuf
members, that's what they are for:
fout << ss.rdbuf();
