Is there anyway I can transfer data from an fstream
(a file) to a stringstream
(a stream in the memory)?
Currently, I'm using a buffer, but this requires double the memory, because you need to copy the data to a buffer, then copy the buffer to the stringstream, and until you delete the buffer, the data is duplicated in the memory.
std::fstream fWrite(fName,std::ios::binary | std::ios::in | std::ios::out);
fWrite.seekg(0,std::ios::end); //Seek to the end
int fLen = fWrite.tellg(); //Get length of file
fWrite.seekg(0,std::ios::beg); //Seek back to beginning
char* fileBuffer = new char[fLen];
fWrite.read(fileBuffer,fLen);
Write(fileBuffer,fLen); //This writes the buffer to the stringstream
delete fileBuffer;`
Does anyone know how I can write a whole file to a stringstream without using an inbetween buffer?
