Name
mkdirat — create a directory relative to a directory
file descriptor
Synopsis
int
mkdirat( |
int |
dirfd, |
| |
const char * |
pathname, |
| |
mode_t |
mode); |
DESCRIPTION
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
mkdirat() was added to Linux
in kernel 2.6.16.
CONFORMING TO
This system call is non-standard but is proposed for
inclusion in a future revision of POSIX.1.
NOTES
See openat(2) for an
explanation of the need for mkdirat().
