NAME

       statvfsdev(), fstatvfsdev() - get file system information

SYNOPSIS

DESCRIPTION

       returns information about the file system on the device file specified by path.	The file system need not be mounted.

       returns similar information for an open file.

       The parameters for the and functions are as follows:

	      path	is a pointer to the name of the device file.  (All directories listed in the path name must be searchable.)

	      buf	is a pointer to a structure, which is where the file status information is stored.

	      fildes	is  a file descriptor for an open file, which is created with the successful completion of an or system call (see open(2),
			creat(2), dup(2), fcntl(2), or pipe(2)).

       buf is a pointer to a structure into which information is placed concerning the file system.  The contents of the structure pointed  to	by
       buf are described in statvfs(2).

       returns the same information as above, but about the open device file referred to by file descriptor fildes.

RETURN VALUE

       Upon successful completion, and return zero.  Otherwise, they return -1 and set the global variable to indicate the error.

ERRORS

       If fails, is set to one of the following values:

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

	      path		  points to an invalid address.

	      Too many symbolic links are encountered during path-name translation.

	      The maximum number of file descriptors allowed are currently open.

	      The length of the specified path name exceeds
				  bytes, or the length of a component of the path name exceeds bytes while is in effect.

	      The system file table is full.

	      The named file does not exist.

	      A component of the path prefix is not a directory.

	      The device specified by the named special file does not exist.

	      Result would overflow one or more fields of the
				  struct.

       If fails, is set to one of the following values:

	      fildes		  is not a valid open file descriptor.

	      filedes		  is invalid.

       When both and fail, is set to one of the following values:

	      A system call was interrupted by a signal.

	      The file specified by
				  path or filedes does not contain a file system of any known type.

	      Check with your system administrator to make sure the
				  is running properly on your system.
