int statfs(
/* SYNOPSIS */
const char *path,
struct statfs *buf)
/* FUNCTION
Gets information about mounted filesystem.
INPUTS
path - path to any file in the filesystem we want to know about
buf - pointer to statfs structures where information about filesystem
will be stored
RESULT
Information about filesystem is stored in statfs structure
NOTES
EXAMPLE
BUGS
f_flags, f_files, f_ffree and f_fsid.val are always set to 0
f_mntfromname is set to an empty string
