| |
| <p>Darwin targets support the <code>CFString</code> (or <code>__CFString__</code>) in the format |
| attribute context. Declarations made with such attribution are parsed for correct syntax |
| and format argument types. However, parsing of the format string itself is currently undefined |
| and is not carried out by this version of the compiler. |
| |
| <p>Additionally, <code>CFStringRefs</code> (defined by the <code>CoreFoundation</code> headers) may |
| also be used as format arguments. Note that the relevant headers are only likely to be |
| available on Darwin (OSX) installations. On such installations, the XCode and system |
| documentation provide descriptions of <code>CFString</code>, <code>CFStringRefs</code> and |
| associated functions. |
