This bug fix got our app past its first problem with > 2 Gig files, but
then it tripped over ftello. I'm still trying to figure that one out.
It looks like it got a 32 bit sign extended value somewhere. Any help would
be appreciated. Thanks.
Well, that somewhere is ftello64.c line 111. fp->_offset has a 32 bit
sign extended value. Anybody know how it got there?
That can't be it. fp is of type FILE which is actually mapped to
__sFILE64 in 64 bit case. See newlib/libc/include/sys/reent.h.
_offset is of type _off64_t there.
I think you misunderstood. fp->_offset is a 64 bit type, but at the
ftello call in question, it contains a value that must have come from a 32
bit sign extension. That's why I asked for help, because I have to figure
out what/who put it there.
I have attached a test case that shows the problem. It is on line 58 of
lseekr.c.
I can't seem to find the actual problem tonight and I'm tired so I'm going
home.
