Specify the root of help topic paths
void PtHelpTopicRoot( char *topic );
PtHelpTopicRoot() lets you specify a partial root topic path that's prefixed to any relative topic paths in subsequent PtHelpTopic() calls. (Any path that doesn't start with a / is considered relative.)
|PtHelpTopicRoot() doesn't copy the topic root. Don't free the string until you've finished using the root topic path.|
