SETQUOTA(2) — SYSTEM CALLS
NAME
setquota − enable/disable quotas on a file system
SYNOPSIS
setquota(special, file)
char ∗special, ∗file;
DESCRIPTION
N.B.: This call is not implemented in the current version of the system.
Disc quotas are enabled or disabled with the setquota call. Special indicates a block special device on which a mounted file system exists. If file is nonzero, it specifies a file in that file system from which to take the quotas. If file is 0, then quotas are disabled on the file system. The quota file must exist; it is normally created with the quotacheck(8) program.
Only the super-user may turn quotas on or off.
SEE ALSO
quota(2), quotacheck(8), quotaon(8)
RETURN VALUE
A 0 return value indicates a successful call. A value of −1 is returned when an error occurs and errno is set to indicate the reason for failure.
ERRORS
Setquota will fail when one of the following occurs:
[ENODEV] The caller is not the super-user.
[ENODEV] Special does not exist.
[ENOTBLK] Special is not a block device.
[ENXIO] The major device number of special is out of range (this indicates no device driver exists for the associated hardware).
[EPERM] The pathname contains a character with the high-order bit set.
[ENOTDIR] A component of the path prefix in file is not a directory.
[EROFS] File resides on a read-only file system.
[EACCES] File resides on a file system different from special.
[EACCES] File is not a plain file.
BUGS
The error codes are in a state of disarray; too many errors appear to the caller as one value.
