STATVFS(2)		    BSD System Calls Manual		    STATVFS(2)

NAME
     statvfs, fstatvfs, — get file system statistics

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <sys/statvfs.h>

     int
     statvfs(const char *path, struct statvfs *buf);

     int
     fstatvfs(int fd, struct statvfs *buf);

DESCRIPTION
     statvfs() returns information about a mounted file system.	 path is the
     path name of any file within the mounted file system.  buf is a pointer
     to a statvfs structure defined in statvfs(5).

     fstatvfs() returns the same information about an open file referenced by
     descriptor fd.

RETURN VALUES
     Upon successful completion, a value of 0 is returned.  Otherwise, -1 is
     returned and the global variable errno is set to indicate the error.

ERRORS
     statvfs() fails if one or more of the following are true:

     [ENOTDIR]		A component of the path prefix of path is not a direc‐
			tory.

     [ENAMETOOLONG]	The length of a component of path exceeds NAME_MAX
			characters, or the length of path exceeds PATH_MAX
			characters.

     [ENOENT]		The file referred to by path does not exist.

     [EACCES]		Search permission is denied for a component of the
			path prefix of path.

     [ELOOP]		Too many symbolic links were encountered in translat‐
			ing path.

     [EFAULT]		buf or path points to an invalid address.

     [EIO]		An I/O error occurred while reading from or writing to
			the file system.

     fstatvfs() fails if one or more of the following are true:

     [EBADF]		fd is not a valid open file descriptor.
