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.

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
