System Functions (k - m) mknod(2)

[EEXIST] The named ﬁle exists.

[EFAULT] The path parameter points outside the process’s allocated address space.

[EFSBAD] The ﬁleset catalog for one of the ﬁlesets involved in the operation is corrupt.

[EINVAL] One of the following conditions exists:

• The value S_IFBLK was speciﬁed for the mode parameter.

• A value other than 0 (zero) was speciﬁed for the device parameter when

a value other than S_IFCHR was speciﬁed for the mode parameter.

• An invalid value was speciﬁed for the device parameter when the value

S_IFCHR was speciﬁed for the mode parameter.

• The mode parameter speciﬁes a ﬁle type of S_IFDIR but the path

parameter speciﬁes a pathname of the form /G/vol.

• The mode parameter speciﬁes a ﬁle type of S_IFIFO but the path

parameter speciﬁes a pathname in /G (the Guardian ﬁle system).

[EIO] During an access of the ﬁle system, an I/O error occurred.

[ELOOP] Too many symbolic links were encountered in resolving the value of the path

parameter.

[ENAMETOOLONG]

One of the following is too long:

• The pathname pointed to by the path parameter

• A component of the pathname pointed to by the path parameter

• The intermediate result of pathname resolution when a symbolic link is

part of the pathname pointed to by the path parameter

The pathconf( ) function can be called to obtain the applicable limits.

[ENOENT] One of the following conditions exists:

• The named directory does not exist.

• The speciﬁed pathname is an empty string.

• The speciﬁed pathname cannot be mapped to a valid Guardian ﬁlename.

• The path parameter includes a symbolic link, but the ﬁle to which it

refers does not exist.

• The path parameter speciﬁes a ﬁle on a remote HP NonStop node but

communication with the remote node has been lost.

[ENOROOT] The root ﬁleset (ﬁleset 0) is not in the STARTED state.

[ENOSPC] The directory that would contain the new ﬁle cannot be extended, or the ﬁleset is

out of resources.
