This function is declared in @code{rtems/rtems_bsdnet.h}.
+t returns 0 on success and -1 on failure with an error code
+in @code{errno}. It is not possible to undo the effects of
+a partial initialization, though, so the function can be
+called only once irregardless of the return code. Consequently,
