Question

Sir,
I have used filelength function in C as follows,

long l;
l=filelength(fileno(fp))

The result is not correct for files having length greater than integer's max size (in bytes).

What to do .  

Answer
For that, you will have to write your own function filelength_long().
And finding a file size is not a big thing.
Open the file. Goto the end of the file and do ftell() and you will get the size.
Or you can use stat/lstat/fstat functions to get the size.
