About QFile::map(...) something has been broken in Qt 4.6 rc1 for OS X.
No problem under Windows.
The following code was wroking before:
QFile file("/myfile");
file.open(QIODevice::ReadWrite | QIODevice::Truncate | QIODevice::Unbuffered);
char buf[100];
memset(buf, 0, 100);
file.write(buf, 100);
uchar* p = file.map(0, 100);now p is NULL !!! By comparing the code in beta1 and rc1, I see some modification in qfsfileengine_unix.cpp. The problem is about this code which has been added: if (doStat() && (QT_OFF_T(size) > st.st_size - QT_OFF_T(offset))) return 0; The problem is that "st.st_size" is 0 because it does not take into account the recently written data.
