PtHelpTopicTree() tells the Helpviewer to load a new topic
tree. The argument must be a top-level topic file with the
.toc extension. The format of the topic file is defined
in
“Creating topic files”
in the Helpviewer documentation in the
QNX Neutrino Utilities Reference.
PtHelpTopicTree() spawns the
Helpviewer if it isn't running, or sends a message to the
Helpviewer if it is.
0 on success, or -1 if the Helpviewer couldn't be found or spawned.

PtHelpTopicTree() returns immediately, before the topic tree has
been displayed. |
