MKNOD(2)                COMMAND REFERENCE                MKNOD(2)



NAME
     mknod - make a special file

SYNOPSIS
     mknod(path, mode, dev)
     char *path;
     int mode, dev;

DESCRIPTION
     The mknod command creates a new special file whose name is
     path.  The mode of the new file (including special file
     bits) is initialized from mode.  (The protection part of the
     mode is modified by the process's mode mask; see umask(2)).
     The first block pointer of the i-node is initialized from
     dev and is used to specify which device the special file
     refers to.

     For a list of modes, see stat(2).

     If mode indicates a block or character special file, dev is
     a configuration-dependent specification of a character or
     block I/O device.  If mode does not indicate a block special
     or character special device, dev is ignored.

     The mknod command may be invoked only by the superuser.

DIAGNOSTICS
     The mknod command fails and the file mode remains unchanged
     if:

     [EPERM]        The process's effective user ID is not
                    superuser.

     [ENOASCII]     The path name contains a character with the
                    high-order bit set.

     [ENAMETOOLONG] The argument path is too long.

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

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

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

     [EEXIST]       The named file already exists.

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

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

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

     [EACCES]       Search permission is denied for any component
                    of the path name.

     [ENFILE]       The system inode table is full.

     [ENOSPC]       The file system is out of inodes.

     [ENOSPC]       The directory in which the entry for the new
                    file is being placed cannot be extended
                    because there is no space left on the file
                    system containing the directory.

RETURN VALUE
     Upon successful completion a value of 0 is returned.
     Otherwise, a value of -1 is returned and errno is set to
     indicate the error.
