fstat_vfs pHILE+ System Calls
Return Value
buf Points to a statvfs structure defined in , as follows:
typedef struct {
long val[2];
} fsid_t;
struct statvfs {
unsigned long f_bsize; /* preferred volume block size */
unsigned long f_frsize; /* fundamental volume block size */
unsigned long f_blocks; /* total number of blocks */
unsigned long f_bfree; /* total number of free blocks */
unsigned long f_bavail; /* free blocks available to
* non-superuser */
unsigned long f_files; /* total # of file nodes
* (pHILE+ files only) */
unsigned long f_ffree; /* reserved (not supported) */
unsigned long f_favail; /* reserved (not supported) */
fsid_t f_fsid; /* reserved (not supported) */
char f_basetype[16]; /* reserved (not supported) */
unsigned long f_flag; /* reserved (not supported) */
unsigned long f_namemax; /* reserved (not supported) */
char f_fstr[32]; /* reserved (not supported) */
unsigned long f_fstype; /* file system type number */
unsigned long f_filler[15];/* reserved (not supported) */
};
This structure cannot be packed. Currently, the fields f_ffree,
f_favail, f_fsid, f_basetype, f_flag, f_namemax, f_fstr and
f_filler are reserved and do not have values. For all volumes except
pHILE+ format, the field f_files is unused.
The field f_fstype identifies the type of file system format. The values
in are given below:
FSTYPE_PHILE pHILE+ format volume
FSTYPE_PCDOS MS-DOS format volume
FSTYPE_CDROM CD-ROM format volume
FSTYPE_NFS Client NFS volume
The return value for all unsupported fields is 0.
This system call returns 0 on success or an error code on failure.
