high-order bit set", as this error is obsolete. Eventually we may want to add code to some of the "optional" filesystems (msdosfs, etc.) that checks for illegal characters. At that time it would be appropriate to reintroduce this error with appropriate text. Perhaps "The pathname contains a character that is not valid for filesystem type".

.Sh NAME
|
|
.Nm bind
|
|
.Nd bind a name to a socket
|
|
.Sh SYNOPSIS
|
|
.Fd #include <sys/types.h>
|
|
.Fd #include <sys/socket.h>
|
|
.Ft int
|
|
.Fn bind "int s" "struct sockaddr *name" "int namelen"
|
|
.Sh DESCRIPTION
|
|
.Fn Bind
|
|
assigns a name to an unnamed socket.
|
|
When a socket is created
|
|
with
|
|
.Xr socket 2
|
|
it exists in a name space (address family)
|
|
but has no name assigned.
|
|
.Fn Bind
|
|
requests that
|
|
.Fa name
|
|
be assigned to the socket.
|
|
.Sh NOTES
|
|
Binding a name in the UNIX domain creates a socket in the file
|
|
system that must be deleted by the caller when it is no longer
|
|
needed (using
|
|
.Xr unlink 2 ) .
|
|
.Pp
|
|
The rules used in name binding vary between communication domains.
|
|
Consult the manual entries in section 4 for detailed information.
|
|
.Sh RETURN VALUES
|
|
If the bind is successful, a 0 value is returned.
|
|
A return value of -1 indicates an error, which is
|
|
further specified in the global
|
|
.Va errno .
|
|

parameter is not in a valid part of the user
