    C Library For Filesystem information?

    Hey all,
    I was looking for a C library to give me filesystem information just like the "df -h" command does. I don't want to shell out and call it with system() to make it as efficient as possible. Are there any libraries that will allow me to do this? My OS is Solaris.

    I'm pretty sure there is a system service that provides that somehow. Have you tried doing "strace df -h" to see what it actually does [it may of course do LOTS of irrelevant stuff, but somewhere, probably close to the write(1, ...) bit that output the result, you will most likely see a system call or such that figures out what space is available on the disk.

    Compilers can produce warnings - make the compiler programmers happy: Use them!
    Please don't PM me for help - and no, I don't do help over instant messengers.

    You could just look at the source code for open solaris anyway.
