) -> otError
Expand description

Sets additional options to append at the end of emitted Router Advertisement (RA) messages.

The content of @p aOptions is copied internally, so it can be a temporary buffer (e.g., a stack allocated array).

Subsequent calls to this function overwrite the previously set value.

@param[in] aOptions A pointer to the encoded options. Can be NULL to clear. @param[in] aLength Number of bytes in @p aOptions.

@retval OT_ERROR_NONE Successfully set the extra option bytes. @retval OT_ERROR_NO_BUFS Could not allocate buffer to save the buffer.
