C Program to calculate the FILE Size Sytem in Unix

Hi All,
I am trying to write a C program to calculate the Unix FILE System Size and Free Size available in Unix
i am not able to finish program..

is it anyone have any idea or any thought.

please share with me.

Thanks in Advance,

Anwar

file size is pretty easy -- use stat() function. Don't know about getting amount of free disk space.

Hi

THanks for response. i have tried with stat and fstat also.
but basically my req. is like that

i want to know the following directory

free space and size of the directory sturcture

for example output should be like that
i mean user input is directory path or name
and out put is
directroy - /countrys/rakeshs/download -
free size - 2325345456
total space - 344354567

pls let me know how will proceed.
coz fstat will calcuate only file size.

regards,
Anwar

to get the sum of the file sizes in a directory, call opendir() and readdir(). Call fstat() or stat() for each filename retrieved by readdir. see man pages or google for info about those functions.

Hi
Thanks for reply.But i want total size of directory.
i mean free space size also.

is it any way to calculate that.



Thanks

I don't think you can set the max size of a directory. I know you can set the max disk space that any user can use, but I don't think it can be done by directory.

the freespace of a directory is the freespace of the filesystem it sits on (normally) unless you use a quota system (something I haven't delt with myself yet).
