Vl-warn-delta

Add a warning to a delta.

Signature

(vl-warn-delta warning &key (delta 'delta)) → delta

Arguments

warning — Guard (vl-warning-p warning).

delta — Guard (vl-delta-p delta).

Returns

delta — Type (vl-delta-p delta).

Usually you will want to use dwarn instead because it allows you to construct the warning inline. But, occasionally, the warning to add has already been constructed, in which case vl-warn-delta is what you want.
