[Octave-bug-tracker] [bug #66399] fseek and ftell functions don't always work correctly on Win11

[MikeMcC]

Follow-up Comment #4, bug #66399 (group octave):

Sure, I can do that, but let me show you this first.  Here is a directory
listing of all the data files in my working directory, including the file in
my original question:

>> ls -l -S *.dat -r
-rw-r--r-- 1 mmccully None    6400000 Aug 14 16:12
'Data_Md1Seg256Ch1Rng'$'\302\261''1000mVSR4G_1_2.dat'
-rw-r--r-- 1 mmccully None    6400000 Aug 14 16:11
'Data_Md1Seg256Ch1Rng'$'\302\261''1000mVSR4G_1_1.dat'
-rw-r--r-- 1 mmccully None   25690112 Aug  9 16:37
'Data_256Seg'$'\302\261''200mVRng4GSampRate_1_1.dat'
-rw-r--r-- 1 mmccully None  244056064 Aug  5 13:22
'Data_256Seg'$'\302\261''50mVRng4GSampRate_1_1.dat'
-rw-r--r-- 1 mmccully None 1785462784 Aug  6 20:16
'Data_256Seg'$'\302\261''50mVRng4GSampRate_1_2.dat'
-rw-r--r-- 1 mmccully None 2299265024 Aug  8 16:30
'Data_256Seg'$'\302\261''1000mVRng4GSampRate_1_1.dat'
>> 

The files are listed by increasing order of size, as you can see.  The two
reasons for the listing are:
(1) I processed all of the other files without any fseek() or ftell() errors,
and
(2) The largest file, the one in my original question, is the only one that
has a size that translates into a negative 32-bit number.

My apologies for not clarifying before that I didn't have trouble with files
with a size <= 0x7FFFFFFF.

At any rate, I can send a portion of the file you asked about, and I can
truncate it to any size you want.

Thanks...
