The initialized CFStringInlineBuffer structure in which the characters are stored. You should initialize the structure with the
Init Inline Buffer(_: _: _:)
The location of a character in the in-line buffer
buf. This index is relative to the range specified when
A Unicode character, or
0 if a location outside the original range is specified.
This function accesses one of the characters of a string written to an in-line buffer. It is typically called from within a loop to access each character in the buffer in sequence. You should initialize the buffer with the
CFString function. The in-line buffer functions, along with the
CFString structure, give you fast access to the characters of a CFString object. The technique for in-line buffer access combines the convenience of one-at-a-time character access with the efficiency of bulk access.
