failbit is being set and I can't figure out why
- by felipedrl
I'm writing a MIDI file loader. Everything is going fine until at some track I get a failbit exception while trying to read from file. I can't figure out why, I've checked the file size and it's ok too.
Upon checking "errno" and it returns "0".
Any ideas?
Thanks.
The snippet follows:
file.read(reinterpret_cast<char*>(&mHeader.id), sizeof(MidiHeader));
mTracks = new MidiTrack[mHeader.nTracks];
for (uint i = 0; i < mHeader.nTracks; ++i)
{
// this read fails on 6th i. I've checked hexadecimal file and it's
// ok so far.
file.read(reinterpret_cast<char*>(&mTracks[i].id), sizeof(uint));
if (file.fail())
{
std::cerr << errno << std::endl;
massert(false);
}
massert(mTracks[i].id == 0x6B72544D);
file.read(reinterpret_cast<char*>(&mTracks[i].size), sizeof(uint));
mTracks[i].size = swapBytes(mTracks[i].size);
mTracks[i].data = new char[mTracks[i].size];
file.read(mTracks[i].data, mTracks[i].size * sizeof(char));
totalBytesRead += 8 + mTracks[i].size;
massert(totalBytesRead <= fileSize);
}
