Take your pick of statfs or statvfs :
AIX 4.1.5 and 4.2.1 :
struct statfs {
long f_version; /* version/type of statfs, 0 for now */
long f_type; /* type of info, zero for now */
long f_bsize; /* optimal file system block size */
long f_blocks; /* total data blocks in file system */
long f_bfree; /* free block in fs */
long f_bavail; /* free blocks avail to non-superuser */
long f_files; /* total file nodes in file system */
long f_ffree; /* free file nodes in fs */
fsid_t f_fsid; /* file system id */
long f_vfstype; /* what type of vfs this is */
long f_fsize; /* fundamental file system block size */
long f_vfsnumber; /* vfs indentifier number */
long f_vfsoff; /* reserved, for vfs specific data offset */
long f_vfslen; /* reserved, for len of vfs specific data */
long f_vfsvers; /* reserved, for vers of vfs specific data */
char f_fname[32]; /* file system name (usually mount pt.) */
char f_fpack[32]; /* file system pack name */
long f_name_max; /* maximum component name length for posix */
};
AIX 4.1.5 :
struct statvfs {
ulong f_bsize; /* preferred file system block size */
ulong f_frsize; /* fundamental file system block size */
ulong f_blocks; /* total # of blocks of f_frsize on file */
/* system */
ulong f_bfree; /* total # of free blocks */
ulong f_bavail; /* # of blocks available to non super user */
ulong f_files; /* total # of file nodes (inode in JFS) */
ulong f_ffree; /* total # of free file nodes */
ulong f_favail; /* # of nodes available to non super user */
fsid_t f_fsid; /* file system id */
char f_basetype[FSTYPSIZ]; /* Filesystem type name (eg. jfs) */
ulong f_flag; /* bit mask of flags */
ulong f_namemax; /* maximum filename length */
char f_fstr[32]; /* filesystem-specific string */
ulong f_filler[16]; /* reserved for future use */
};
AIX 4.2.1 :
struct statvfs {
ulong_t f_bsize; /* preferred file system block size */
ulong_t f_frsize; /* fundamental file system block size */
fsblkcnt_t f_blocks; /* total # of blocks of f_frsize in fs */
fsblkcnt_t f_bfree; /* total # of free blocks */
fsblkcnt_t f_bavail; /* # of blocks available to non super user */
fsfilcnt_t f_files; /* total # of file nodes (inode in JFS) */
fsfilcnt_t f_ffree; /* total # of free file nodes */
fsfilcnt_t f_favail; /* # of nodes available to non super user */
#ifdef _ALL_SOURCE
fsid_t f_fsid; /* file system id */
#else
ulong_t f_fsid; /* file system id */
ulong_t f_fstype; /* file system type */
#endif /* _ALL_SOURCE */
char f_basetype[_FSTYPSIZ]; /* Filesystem type name (eg. jfs) */
ulong_t f_flag; /* bit mask of flags */
ulong_t f_namemax; /* maximum filename length */
char f_fstr[32]; /* filesystem-specific string */
ulong_t f_filler[16];/* reserved for future use */
};
Sorry, no 4.3 here.
