The
mkdirat()
system call operates in exactly the same way as
mkdir(2),
except for the differences described in this manual page.
If the pathname given in
pathname
is relative, then it is interpreted relative to the directory
referred to by the file descriptor
dirfd
(rather than relative to the current working directory of
the calling process, as is done by
mkdir(2)
for a relative pathname).
If
pathname
is relative and
dirfd
is the special value
AT_FDCWD,
then
pathname
is interpreted relative to the current working
directory of the calling process (like
mkdir(2)).
If
pathname
is absolute, then
dirfd
is ignored.
RETURN VALUE
On success,
mkdirat()
returns 0.
On error, -1 is returned and
errno
is set to indicate the error.
ERRORS
The same errors that occur for
mkdir(2)
can also occur for
mkdirat().
The following additional errors can occur for
mkdirat():
EBADF
dirfd
is not a valid file descriptor.
ENOTDIR
pathname
is relative and
dirfd
is a file descriptor referring to a file other than a directory.
VERSIONS

was added to Linux in kernel 2.6.16.
