MKDIR(2)		    BSD Programmer's Manual		      MKDIR(2)

NAME
     mkdir - make a directory file

SYNOPSIS
     #include <sys/types.h>
     #include <sys/stat.h>

     int
     mkdir(const char *path, mode_t mode);

DESCRIPTION
     The directory path is created with the access permissions specified by
     mode and restricted by the the umask(2) of the calling process.

     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.

RETURN VALUES
     A 0 return value indicates success.  A -1 return value indicates an er-
     ror, and an error code is stored in errno.

ERRORS
     Mkdir() will fail and no directory will be created if:

     [ENOTDIR]	 A component of the path prefix is not a directory.

     [EINVAL]	 The pathname contains a character with the high-order bit
		 set.

     [ENAMETOOLONG]
		 A component of a pathname exceeded 255 characters, or an en-
		 tire path name exceeded 1023 characters.

     [ENOENT]	 A component of the path prefix does not exist.

     [EACCES]	 Search permission is denied for a component of the path pre-
		 fix.

     [ELOOP]	 Too many symbolic links were encountered in translating the
		 pathname.

     [EPERM]	 The path argument contains a byte with the high-order bit
		 set.

     [EROFS]	 The named file resides on a read-only file system.

     [EEXIST]	 The named file exists.

     [EMLINK]	 The link count of the parent directory would exceed

     _PC_LINK_MAX.

     [ENOSPC]	 The new directory cannot be created because there is no space
		 left on the file system that will contain the directory.

     [ENOSPC]	 There are no free inodes on the file system on which the di-
		 rectory is being created.

     [EDQUOT]	 The new directory cannot be created because the user's quota
		 of disk blocks on the file system that will contain the di-

		 rectory has been exhausted.

     [EDQUOT]	 The user's quota of inodes on the file system on which the
		 directory is being created has been exhausted.

     [EIO]	 An I/O error occurred while making the directory entry or al-
		 locating the inode.

     [EIO]	 An I/O error occurred while reading from or writing to the
		 file system.

     [EFAULT]	 Path points outside the process's allocated address space.

SEE ALSO
     chmod(2),	stat(2),  umask(2)

STANDARDS
     Mkdir() conforms to IEEE Std 1003.1-1988 (``POSIX'').

BUGS
     Mode bits other than file access permissions are ignored.	This behavior
     may change in future releases.
