Hi,
I am having a problem with ADA Streams.
I need to access a file which is >2Gb and read data from it in chunks.
Firstly I was having problems getting the file size as
Ada.Streams.Stream_IO.Size didn't seem to want to go over Integer'last
(2*31)
Worked fine for files up until the 2Gb range and then it went funny!
I had to call a 'c' routine (returned an Integer64...i.e. 2*63) to get
the file size and decide how many chunks I wanted.
Ok, now I try to read from the huge file....and bang I am getting a
Constraint error. Is this a case that I just can't use ADA Streams on
files bigger then 2*31 bytes??
This is driving me nuts and I don't want to call 'c' routines again
and spoil my ADA :)
Cheers
Alex
