This function works fine for large text files like 100Mb or 1Gb
but failed when I tried to read 6Gb file. This happens on Windows
x64.
The possible reason that it uses read(in char[], size_t) function
and on windows it calls GetFileSize. This function returns file
size as 32 bit value. If you need size for files larger then 4Gb
then this function provides out parameter where you can pass
reference to another 32 bit value. But in DMD 2.067 this function
is called as
auto size = trustedGetFileSize(h, null);
thus we never get correct size for files larget then 4Gb.
Is it a bug?
