Since we currently work only on linux, how about statfs:

---clip from man statfs---

NAME
       statfs, fstatfs - get file system statistics

SYNOPSIS
       #include <sys/vfs.h>

       int statfs(const char *path, struct statfs *buf);
       int fstatfs(int fd, struct statfs *buf);

DESCRIPTION
       statfs  returns  information  about a mounted file system.  path 
is the
       path name of any file within the mounted filesystem.  buf is a 
pointer
       to a statfs structure defined as follows:

              struct statfs {
                 long    f_type;     /* type of filesystem (see below) */
                 long    f_bsize;    /* optimal transfer block size */
                 long    f_blocks;   /* total data blocks in file system */
                 long    f_bfree;    /* free blocks in fs */
                 long    f_bavail;   /* free blocks avail to 
non-superuser */
                 long    f_files;    /* total file nodes in file system */
                 long    f_ffree;    /* free file nodes in fs */
                 fsid_t  f_fsid;     /* file system id */
                 long    f_namelen;  /* maximum length of filenames */
                 long    f_spare[6]; /* spare for later */
              };
---end clip---
