Function CFStringInitInlineBuffer 

pub unsafe fn CFStringInitInlineBuffer(
    str_: CFStringRef,
    buf: *mut CFStringInlineBuffer,
    range: CFRange,
)

Initializes a CFStringInlineBuffer for indexed character access. Wraps CFStringInitInlineBuffer.

Safety

str_ must be a valid CFStringRef, buf must point to writable storage, and range must describe a valid slice of str_.
