typedef struct statvfs {
u_long f_bsize;
u_long f_frsize;
fsblkcnt_t f_blocks;
fsblkcnt_t f_bfree;
fsblkcnt_t f_bavail;
fsfilcnt_t f_files;
fsfilcnt_t f_ffree;
fsfilcnt_t f_favail;
u_long f_fsid;
char f_basetype[FSTYPSZ];
u_long f_flag;
u_long f_namemax;
char f_fstr[32];
fsblkcnt_t f_bminavail;
fsblkcnt_t f_bmaxavail;
u_long f_filler[5];
