<sys/statvfs.h>(P)		    POSIX Programmer's Manual		       <sys/statvfs.h>(P)

NAME
       sys/statvfs.h - VFS File System information structure

SYNOPSIS
       #include <sys/statvfs.h>

DESCRIPTION
       The  <sys/statvfs.h>  header shall define the statvfs structure that includes at least 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 shall be defined as described in <sys/types.h> .

       The following flags for the f_flag member shall be defined:

       ST_RDONLY
	      Read-only file system.

       ST_NOSUID
	      Does not support the semantics of the ST_ISUID and ST_ISGID file mode bits.

       The following shall be declared as functions and may also be defined as	macros.  Function
       prototypes shall be provided.

	      int statvfs(const char *restrict, struct statvfs *restrict);
	      int fstatvfs(int, struct statvfs *);
