Hi,
This is what I am trying to do - If the filename is given I have to read
from the file else I have to read from cin. The program below compiles fine
but while reading from cin, it reads some part of the stream fine but
encounters an EOF prematuerly. If I read from the cin in a file I see the
full data. So I know that cin does get all the data, just that the read
function behaves in an unexpected way.
std::istream* myFile; // stream object to read the cin
std::filebuf* myFileBuf; // specifies a streamBuffer
.......
if (!myFileName)
{
myFile = &std::cin;
}
else
{
myFileBuf = new std::filebuf;
if (!(myFileBuf->open (myFileName, std::ios::in | std::ios::binary)))
{
status = My_FileOpenErr;
}
else
{
myFile = new std::istream (myFileBuf);
}
}
.........
Then I have the read function
if (!(myFile->read (reinterpret_cast<char*>(mydata), nBytes)))
{
if (myFile->eof())
{
status = My_EndOfFile;
}
else
{
status = My_IOErr;
}
}
Please help,
Thanks in advance.
