On error, \-1 is returned, and
.I errno
is set appropriately.
.SH ERRORS
.TP
.B EACCES
Write access to the directory containing
.I pathname
was not allowed, or one of the directories in the path prefix of
.IR pathname
did not allow search permission.
(See also
.BR path_resolution (7).
.TP
.B EBUSY
.I pathname
is currently in use by the system or some process that prevents its
removal.
On Linux this means
.I pathname
is currently used as a mount point
or is the root directory of the calling process.
.TP
.B EFAULT
.IR pathname " points outside your accessible address space."
.TP
.B EINVAL
.I pathname
has
.I .
as last component.

.TP
.B ENOENT
A directory component in
.I pathname
does not exist or is a dangling symbolic link.
.TP
.B ENOMEM

.TP
.B ENOTDIR
.IR pathname ,
or a component used as a directory in
.IR pathname ,
is not, in fact, a directory.

.B ENOTEMPTY
.I pathname
contains entries other than
.IR . " and " .. " ;"
or,
.I pathname
has
.IR ..
as its final component.
.TP
.B EPERM
The directory containing
.I pathname
has the sticky bit
.RB ( S_ISVTX )
set and the process's effective user ID is neither the user ID
of the file to be deleted nor that of the directory containing it,
and the process is not privileged (Linux: does not have the
.B CAP_FOWNER
capability).
.TP
.B EPERM
The filesystem containing
.IR pathname
does not support the removal of directories.
.TP
.B EROFS
.I pathname
refers to a file on a read-only filesystem.
.SH "CONFORMING TO"
SVr4, 4.3BSD, POSIX.1-2001.
