That one's in the manual.  If you do this:

	C:\> Info libc.a Alphabetical statfs

you will see this:

------------------- begin enclosed material --------------------------

File: libc,  Node: statfs,  Next: stdin/stdout/stderr/stdprn/stdaux,  Prev: stat
_assist,  Up: Alphabetical List

`statfs'
========

Syntax
------

     #include <sys/vfs.h>

     int statfs(const char *filename, struct statfs *buf);

Description
-----------

This function returns information about the given "filesystem".  The
drive letter of the given FILENAME, or the default drive if none is
given, is used to retrieve the following structure:

     struct statfs
     {
         long   f_type;   /* 0 */
         long   f_bsize;  /* bytes per cluster */
         long   f_blocks; /* clusters on drive */
         long   f_bfree;  /* available clusters */
         long   f_bavail; /* available clusters */
         long   f_files;  /* clusters on drive */
         long   f_ffree;  /* available clusters */
         fsid_t f_fsid;   /* [0]=drive_number, [1]=MOUNT_UFS
         long   f_magic;  /* FS_MAGIC */
     };

Return Value
------------

Zero on success, nonzero on failure.

Example
-------

     struct statfs fs;
     statfs("anything", &fs);
     printf("%d bytes left\n", fs.f_bfree * fs.f_bsize);

The name of the structura and its contents are different, though,
from what you will see on a Unix box, so its portability, not
surprisingly, is, er, limited...
