fseek problem files >2Gb (32-bit compile)

Code: Select all

FILE *fp;
int offset;
fseek(fp,offset,SEEK_SET);
When the file is >2Gb it crashes.

Changing int offset; to:

Code: Select all

unsigned int offset;
unsigned long long offset; (64 bit in my compiler)
Doesn't help, same crash.

Is there a way out?

Re: What engine breaks even with GMs in blitz?

I found 2 games of Fritz 2 from 1992. Scoring 1-1 Playing GM Kasparov. Fritz could be playing on a 386 or 486 processor in 1992. My guess would be the 486.

Re: Elements of the ULTIMATE Chess GUI?

Many of the ideas you mentioned I would love to see them in a GUI as well but it seems to me the nature of the ideas fit better in a database program like SCID.

Hi Ed

Is there any possibility to edit the positions of the tool and add or remove positions?

Thank you
Yes, but you need a special version of SIM3 including the source code. I am not allowed to share it.

SIM new version

Recently (after 5 years) I tested the current top-engines on similarity (once again) because I wanted to know 2 things: 1. if the crazy days of the Fruit cloning (2005-2010) and Rybka3 cloning (2010-2015) were over and how the situation anno 2019 is now that Stockfish is the ideal target. And so I r...

Re: Experiment 11 - Similarity between the top engines back then and now.

Found the trouble with Booot, made some changes to SIM3 and Booot became alive, Fizbo unfortunately not. "go movetime" and "go depth" will not work with Fizbo. But it would work using "go infinite". Tested it on 100ms but it would not complete engine would exit. Currently testing it at 200ms, no pr...

Re: Some x64 assembler for the curious

I guess this is the most telling. Traversing all the squares of a slider in capture only mode on an empty board using two moves and a jump. wbcns: movsx ebx,[bns+esi+ebx] mov edx,[brd+ebx*4] jmp [wbcf+edx*4] It is impossible for any C compiler to beat that! This is typically what humans do when the...
