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
rfstatfs64 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.
