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.
