pub unsafe extern "C-unwind" fn CFAttributedStringGetMutableString(
a_str: Option<&CFMutableAttributedString>,
) -> Option<CFRetained<CFMutableString>>Available on crate features
CFAttributedString and CFBase only.Expand description
Gets the string for the attributed string as a mutable string, allowing editing the character contents of the string as if it were an CFMutableString. Attributes corresponding to the edited range are appropriately modified. If, as a result of the edit, new characters are introduced into the string, they inherit the attributes of the first replaced character from range. If no existing characters are replaced by the edit, the new characters inherit the attributes of the character preceding range if it has any, otherwise of the character following range. If the initial string is empty, the attributes for the new characters are also empty.
(Note: This function is not yet implemented and will return NULL except for toll-free bridged instances.)
