mmkknnoodd - make a special file node
SSYYNNOOPPSSIISS
##iinncclluuddee <<uunniissttdd..hh>>
_i_n_t
mmkknnoodd(_c_o_n_s_t _c_h_a_r _*_p_a_t_h, _m_o_d_e___t _m_o_d_e, _d_e_v___t _d_e_v)
DDEESSCCRRIIPPTTIIOONN
The device special file _p_a_t_h is created with the major and minor device
numbers extracted from _m_o_d_e_. The access permissions of _p_a_t_h are descen-
dant from the umask(2) of the parent process.
If _m_o_d_e indicates a block or character special file, _d_e_v is a configura-
tion dependent specification of a character or block I/O device and the
superblock of the device. If _m_o_d_e does not indicate a block special or
character special device, _d_e_v is ignored.
MMkknnoodd() requires super-user privileges.
RREETTUURRNN VVAALLUUEESS
Upon successful completion a value of 0 is returned. Otherwise, a value
of -1 is returned and _e_r_r_n_o is set to indicate the error.
EERRRROORRSS
MMkknnoodd() will fail and the file will be not created if:
[ENOTDIR] A component of the path prefix is not a directory.
[ENAMETOOLONG]
A component of a pathname exceeded {NAME_MAX} characters,
or an entire path name exceeded {PATH_MAX} characters.
[ENOENT] A component of the path prefix does not exist.
[EACCES] Search permission is denied for a component of the path
prefix.
[ELOOP] Too many symbolic links were encountered in translating the
pathname.
[EPERM] The process's effective user ID is not super-user.
[EIO] An I/O error occurred while making the directory entry or
allocating the inode.
[ENOSPC] The directory in which the entry for the new node is being
placed cannot be extended because there is no space left on
the file system containing the directory.
[ENOSPC] There are no free inodes on the file system on which the
node is being created.
[EDQUOT] The directory in which the entry for the new node is being
placed cannot be extended because the user's quota of disk
blocks on the file system containing the directory has been
exhausted.
[EDQUOT] The user's quota of inodes on the file system on which the
node is being created has been exhausted.
[EROFS] The named file resides on a read-only file system.
[EEXIST] The named file exists.
[EFAULT] _P_a_t_h points outside the process's allocated address space.
