pub unsafe extern "C-unwind" fn CFAttributedStringGetAttribute(

) -> Option<CFRetained<CFType>>Available on crate features
CFAttributedString and CFBase only.Expand description
Returns the value of a single attribute at the specified location. If the specified attribute doesn’t exist at the location, returns NULL. If effectiveRange is not NULL, upon return *effectiveRange contains a range over which the exact same attribute value applies. Note that for performance reasons, the returned effectiveRange is not necessarily the maximal range - for that, use CFAttributedStringGetAttributeAndLongestEffectiveRange(). It’s a programming error for loc to specify a location outside the bounds of the attributed string.
