Open System Services System Calls Reference Manual (G06.25+, H06.03+)

System Functions (k - m) link(2)

• A component of the pathname pointed to by the path1 parameter

• A component of the pathname pointed to by the path2 parameter

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

part of the path1 or path2 parameter

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

[ENOENT] One of the following is true:

• The ﬁle speciﬁed by the path1 parameter does not exist.

• The path1 or path2 parameter is an empty string.

• The path1 parameter names a symbolic link, but the ﬁle to which it

refers does not exist.

• The path1 or path2 parameter speciﬁes a ﬁle on a remote HP NonStop

node but communication with the remote node has been lost.

[ENOROOT] One of the following conditions exists:

• The root ﬁleset of the local node (ﬁleset 0) is not in the STARTED state.

• The current root ﬁleset for the speciﬁed ﬁle is unavailable. The OSS

name server for the ﬁleset might have failed.

• The speciﬁed ﬁle is on a remote HP NonStop node and communication

with the remote name server has been lost.

[ENOSPC] The directory in which the entry for the new link is being placed cannot be

extended, because there is no space left on the ﬁleset containing the directory.

[ENOTDIR] A component of either pathname preﬁx is not a directory.

[ENXIO] The ﬁleset containing the client’s current working directory or root directory is

not mounted.

[EOSSNOTRUNNING]

The program attempted an operation on an object in the OSS environment while

a required system process was not running.

[EPERM] One of the following conditions occurred:

• The ﬁle speciﬁed by the path1 parameter is a directory.

• The call attempted to create a link in the root directory of an OSS ﬁleset

to a ﬁle called lost+found.

• The call attempted to create a link to /dev/tty or /dev/null.

[EROFS] The requested link requires writing to a directory on a read-only ﬁleset.

[EXDEV] The link speciﬁed by the path2 parameter and the ﬁle speciﬁed by the path1

parameter are on different ﬁlesets.
