NAME

       rfdf - print information about a mounted filesystem

SYNOPSIS

       rfdf filename ...

DESCRIPTION

       rfdf  provides  an  interface  to the shift remote file I/O daemon (rfiod) for returning information about one or more mounted filesystems.
       The filenames may refer to one ore more remote files or directories, each having the form:

	      hostname:path

       or a local file (not containing the :/ character combination). The information for the filesystem on which each file or	directory  resides
       is returned.

       The following information may be returned

       Path (as specified on the command line)

	      blocksize

	      total blocks

	      free blocks - number of blocks available to non-superuser

	      total inodes

	      free inodes

NAME

       rfio_statfs - get information about a mounted filesystem

SYNOPSIS

       #include <sys/types.h>
       #include "rfio_api.h"

       int rfio_statfs (const char *path, struct rfstatfs *statfsbuf);

       Under Linux, for large files:
       #define _LARGEFILE64_SOURCE
       #include <sys/types.h>
       #include "rfio_api.h"

       int rfio_statfs64 (const char *path, struct rfstatfs64 *statfsbuf);

       For large files, under other systems:
       #include <sys/types.h>
       #include "rfio_api.h"

       int rfio_statfs64 (const char *path, struct rfstatfs64 *statfsbuf);

DESCRIPTION

       rfio_statfs gets information about a mounted filesystem.

       path    specifies the logical pathname relative to the current directory or the full pathname of any file in this filesystem.

       statfsbuf
	       is a pointer to a rfstatfs structure:
	       struct rfstatfs {
		       long totblks  ;	    /* Total number of blocks	    */
		       long freeblks ;	    /* Number of free blocks	    */
		       long bsize    ;	    /* Block size		    */
		       long totnods  ;	    /* Total number of inodes	    */
		       long freenods ;	    /* Number of free inodes	    */
	       };
	       struct rfstatfs64 {
		       signed64 totblks  ;  /* Total number of blocks	    */
		       signed64 freeblks ;  /* Number of free blocks	    */
		       long bsize	 ;  /* Block size		    */
		       signed64 totnods  ;  /* Total number of inodes	    */
		       signed64 freenods ;  /* Number of free inodes	    */
	       };

       The  64	bits  function must be used for large filesystems. It has the same syntax as the normal statfs function except that it uses a rfs-
       tatfs64 structure.

RETURN VALUE

       This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

ERRORS

       ENOENT	    The named file/directory does not exist or is a null pathname.

       EACCES	    Search permission is denied on a component of the path prefix.

       EFAULT	    path or statfsbuf is a NULL pointer.

       ENOTDIR	    A component of path prefix is not a directory.

       ENAMETOOLONG The length of path exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.
