[Dev-C++] read system call

[A.Bhuvaneswaran <bh...@sy...>]

Hi,

I am using win xp home edition.

I am new to windows. I am trying to read data from a binary file using
open, lseek & read system calls. But, read returns 0 bytes at certain
point, even though it has not reached the eof.

For example, if the file size is 400k and if i try to read from 2k to
300k, 1k at a time, read returns 0 (indicating eof, right ?) after
reading 51k.

I have tried the same code on gnu linux and it works perfect.

Could you please let me know what am i doing wrong over here ? Googling
and search in the archive does not help.

TIA.

I will be glad to submit repeatable tiny sample code, if required.

Past week I see this problem. Set option for open file O_BINARY.
