<h4 class="subsection">6.59.2 Darwin Format Checks</h4>
|
|
|
|
<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.
