Re: [Boost-users] boost::filesystem::ifstream and .eof()

Hi! pktao@uwm.edu schrieb:

while ( !inputDataStream.eof() ) {

if ( (previousIterator + 3) == i) {

immobileWrite(i);

previousIterator = previousIterator + 3;

else {

dataStructureWrite(i);

i++;

};

I cannot see where data is read. Anyway: - first: Test for any error: "while(inputDataStream) {...}" - second: Test after read: int sum = 0, i; while(inputDataStream >> i) { sum +=i; } When using istream_iterator<T>, then just test against an end interator: std::for_each(istream_iterator<int>(inputDataStream), istream_iterator<int>(), &foo); All of the above is true for both boost::filesystem::basic_ifstream and std::ifstream. It is true for any std::istream. HTH, Frank
