<p>Function pointer for a regular expression find callback function. </p>
<p>When set, a callback function will be called during a find operation and for operations that depend on find, such as findNext, split and some replace operations like replaceFirst. The callback will usually be called after each attempt at a match, but this is not a guarantee that the callback will be invoked at each character. For finds where the match engine is invoked at each character, this may be close to true, but less likely for more optimized loops where the pattern is known to only start, and the match engine invoked, at certain characters. When invoked, this callback will specify the index at which a match operation is about to be attempted, giving the application the opportunity to terminate a long-running find operation.</p>
<p>If the call back function returns FALSE, the find operation will be terminated early.</p>
