mkdirat
() works the same way as
mkdir
() except if path is
relative. In that case, it is looked up from a directory whose file
descriptor was passed as fd. Search permission is
required this directory. fd can be set to
AT_FDCWD
in order to specify the current
directory.
The directory's owner ID is set to the process's effective user ID. The directory's group ID is set to that of the parent directory in which it is created.
mkdir
() and mkdirat
()
functions return the value 0 if successful; otherwise the
value -1 is returned and the global variable
errno is set to indicate the error.
mkdir
() and mkdirat
() will
fail and no directory will be created if:
EACCES
]EDQUOT
]EEXIST
]EFAULT
]EIO
]ELOOP
]ENAMETOOLONG
]NAME_MAX
}
characters, or an entire path name exceeded
{PATH_MAX
} characters.ENOENT
]ENOSPC
]ENOTDIR
]EROFS
]In addition, mkdirat
() will fail if:
mkdir
() function conforms to IEEE
Std 1003.1-1990 (“POSIX.1”).
mkdirat
() conforms to IEEE Std
1003.1-2008 (“POSIX.1”).
