通过std::ofstream 类,可以创建一个用于写入文件的输出流对象,可以将数据写入到文件中 下面是一个简单的例子: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 #include <fstream> // 音频回调,也可以在发送音频数据时写入 voidOnAudioData(void* data,intsize,intchannels,i...
unsigned char* pFileBytes = nullptr; unsigned int nTotalSize = 0; std::ifstream infile("1.dat", std::ios_base::in | std::ios_base::binary); if (infile.is_open()) { infile.seekg(0, std::ios_base::end); unsigned long long nFileSize = infile.tellg(); if (0 == nFileSize)...
= data.size()) { std::cerr << "Error writing to file. Expected to write " << data.size() << " bytes, but wrote " << bytesWritten << " bytes." << std::endl; ofs.close(); return 1; } std::cout << "Successfully wrote ...
std::ofstream由二进制流写文件的问题 从MPQ包中读取二进制流出来然后文件写到硬盘。 DWORD size = SFileGetSize(hFile); char* buffer = new char[size]; std::ofstream ofs; ofs.open(name); ASSERT(ofs.good()); ofs.write(buffer, size); ASSERT(ofs.good()); ofs.close(); .xml,.lua,等文本...
fstreams既可以是输入流也可以是输出流。tellg()将返回输入位置，tellp()将告诉您输出位置。在附加到...
while((bytesRead=read(0,buffer,sizeof(buffer)))>0){ file.write(buffer,bytesRead);// 将接收到的数据写入文件 } if(bytesRead==-1){ std::cerr<<"读取输入时出错"<<std::endl; return1; } file.close();// 关闭文件 std::cout<<"数据已成功保存至"<<filename<<std::endl; ...
要将std::string写入文件,可以使用std::ofstream的成员函数write()或者使用输出运算符<<。下面是两种方法的示例: 使用write()函数:#include <fstream> #include <string> int main() { std::ofstream file("example.txt"); std::string str = "Hello, World!"; file.write(str.c_str(), str.size())...
