NAME

       statvfs.h, statvfs - VFS File System information structure

SYNOPSIS

       #include <sys/statvfs.h>

DESCRIPTION

       The <sys/statvfs.h> header defines the statvfs structure, which includes the following members:

       unsigned long f_bsize	 /* file system block size */
       unsigned long f_frsize	 /* fundamental file system block size */
       fsblkcnt_t    f_blocks	 /* total number of blocks on file system */
				 /* in units of f_frsize */
       fsblkcnt_t    f_bfree	 /* total number of free blocks */
       fsblkcnt_t    f_bavail	 /* number of free blocks available to */
				 /* non-privileged process */
       fsfilcnt_t    f_files	 /* total number of file serial numbers */
       fsfilcnt_t    f_ffree	 /* total number of free file serial numbers */
       fsfilcnt_t    f_favail	 /* number of file serial numbers available */
				 /* to non-privileged process */
       unsigned long f_fsid	 /* file system ID */
       unsigned long f_flag	 /* bit mask of f_flag values */
       unsigned long f_namemax	 /* maximum filename length */

       The fsblkcnt_t and fsfilcnt_t types are defined as described in <sys/types.h>. See types.h(3HEAD).

       The following flags for the f_flag member are defined:

       ST_RDONLY       read-only file system

       ST_NOSUID       does not support setuid()/setgid() semantics
