STATVFS(5)                  BSD File Formats Manual                 STATVFS(5)

NAME
     statvfs -- file system statistics

SYNOPSIS
     #include <sys/types.h>
     #include <sys/statvfs.h>

DESCRIPTION
     The <sys/statvfs.h> header defines the structures and functions that
     return information about a mounted file system.  The statvfs structure is
     defined as follows:

     struct statvfs {
             unsigned long   f_bsize;  /* system block size */
             unsigned long   f_frsize; /* system fragment size */

             fsblkcnt_t      f_blocks; /* number of blocks in file system */
             fsblkcnt_t      f_bfree;  /* free blocks avail in file system */
             fsblkcnt_t      f_bavail; /* free blocks avail to non-root */

             fsfilcnt_t      f_files;  /* total file nodes in file system */
             fsfilcnt_t      f_ffree;  /* free file nodes in file system */
             fsfilcnt_t      f_favail; /* free file nodes avail to non-root */

             unsigned long   f_fsid;   /* File system ID */

             unsigned long   f_flag;   /* flags */

             unsigned long   f_namemax;/* maximum filename length */
     };

     The f_flag argument can have the following bits set:

     ST_RDONLY       The filesystem is mounted read-only; Even the super-user
                     may not write on it.

     ST_NOSUID       Setuid and setgid bits on files are not honored when they
                     are executed.

     ST_NOTRUNC      File names longer than NAME_MAX are not truncated.
