Hello,
I was recently working on some code where I wanted to use the QtEndian
stuff. I noticed that the functions that take const uchar* seem to do some
unnecessary operations.
For example this function is defined on a little endian target.
template <> inline quint32 qFromLittleEndian<quint32>(const uchar *src)
{
return 0
| src[0]
| src[1] * quint32(0x00000100)
| src[2] * quint32(0x00010000)
| src[3] * quint32(0x01000000);
}
The memory being pointed at is already in little endian order. Why not just
reinterpret_cast instead of performing several operations? Wouldn't that be
faster? What am I missing?
Thanks
