rfio_statfs64 (3)

#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);

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 rfstatfs64 structure.

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

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.
