+\fP
+.SH DESCRIPTION
+.LP
+The \fIif_nameindex\fP() function shall return an array of \fIif_nameindex\fP
+structures, one structure per interface. The end
+of the array is indicated by a structure with an \fIif_index\fP field
+of zero and an \fIif_name\fP field of NULL.
+.LP
+Applications should call \fIif_freenameindex\fP() to release the memory
+that
+may be dynamically allocated by this function, after they have finished
+using it.
+.SH RETURN VALUE
+.LP
+An array of structures identifying local interfaces. A NULL pointer
+is returned upon an error, with \fIerrno\fP set to indicate
+the error.
+.SH ERRORS
+.LP
+The \fIif_nameindex\fP() function may fail if:
+.TP 7
