file unable to open
 

I am unable to open a file using the below code in c++. The code used to work before.
I am running this program in unix (sun c++ v4.2 compilers). The file I am reading currently is now > 2GB. I am able to read files < 2GB using this code. Is it because of a limit on the unix server? Please let me know the issue with this.

FYI, I had the same issue with the file size in perl. But I used pipe | to read files > 2GB.

Can somebody please help me resolve this issue.

cout << buffer << endl;
inFile.close();
