[EIO] The socket is in the AF_UNIX domain, and the transport agent failed to inherit

the ﬁle descriptors being passed, or an input or output error occurred.

[ELOOP] The socket is in the AF_UNIX domain, and too many symbolic links were

encountered in translating the pathname speciﬁed by the msghdr structure.

[EMSGSIZE] The message is too large to be sent all at once, as required by the socket.

[ENAMETOOLONG]

The socket is in the AF_UNIX domain, and one of these conditions exists:

• The pathname in the msghdr structure exceeds PATH_MAX characters.

• A component of the pathname in the msghdr structure exceeds

NAME_MAX characters.

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

part of the pathname in the msghdr structure exceeds PATH_MAX

characters.

You can call the pathconf() function to obtain the applicable limits.

[ENOBUFS] Not enough buffer space was available to complete the call. A retry at a later

time might succeed.

[ENOENT] The socket is in the AF_UNIX domain, and one of these conditions occurred:

• A component of the pathname in the msghdr structure does not name an

existing ﬁle.

• The msghdr structure speciﬁes an empty string as a pathname.

[ENOMEM] Required memory resources were not available. A retry at a later time might

succeed.

[ENOPROTOOPT]

The socket is in the AF_UNIX domain, and the cmsg_level member is not equal

to SOL_SOCKET.

[ENOTCONN] The socket is connection-oriented but is not connected.

[ENOTDIR] The socket is in the AF_UNIX domain, and the pathname speciﬁed by the

msghdr structure contains a component that is not a directory.

[ENOTSOCK] The socket parameter does not refer to a socket.

[EOPNOTSUPP]

The speciﬁed value for the ﬂags parameter is not supported for this socket type

or protocol.

[EPERM] The address included in the message parameter is bound to a socket whose mode

is different than the mode of the socket speciﬁed by the socket parameter.
