.Nd bind a name to a socket
.Sh SYNOPSIS
-.Fd #include <sys/types.h>
.Fd #include <sys/socket.h>
.Ft int

.Sh DESCRIPTION
-.Fn Bind
+.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
+.Fn bind
requests that
-.Fa name
+.Fa address
be assigned to the socket.
.Sh NOTES
Binding a name in the UNIX domain creates a socket in the file
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 .
+Upon successful completion, a value of 0 is returned.
+Otherwise, a value of -1 is returned and the global integer variable
+.Va errno
+is set to indicate the error.
