mkdir(2)                                                 mkdir(2)



NAME
     mkdir - makes a directory file

SYNOPSIS
     int mkdir(path,mode)
     char *path;
     int mode;

DESCRIPTION
     mkdir creates a new directory file with name path.  The mode
     of the new file is initialized from mode.  (The protection
     part of the mode is modified by the process's mode mask; see
     umask(2)).

     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.

     The newly-created directory will contain entries for . and
     ...

     The low-order 9 bits of mode are modified by the process's
     file mode creation mask; all bits set in the process's file
     mode creation mask are cleared (see umask(2)).

STATUS MESSAGES AND VALUES
     A 0 return value indicates success.  A -1 return value
     indicates an error, and an error code is stored in errno.

     The mkdir command will fail and no directory will be created
     if:

     EEXIST
          The named file exists.

     EFAULT
          path points outside the process's allocated address
          space.

     EIO  An I/O error occurred while writing to the file system.

     ELOOP
          Too many symbolic links were encountered in translating
          a pathname.

     ENAMETOOLONG
          A component of a pathname exceeded NAME_MAX characters,
          or an entire pathname exceeded PATH_MAX.

     ENOENT
          A component of the path prefix does not exist.

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

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

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