I noticed that atscppapi::RegisterGlobalPlugin doesn't return any value.
This makes impossible for plugins that use to to know whether they need to
abort initialization or continue after registering the plugin.
I'm proposing to change the method signature to return a boolean value, so
plugins can abort in case of failure.
Example:
```
void TSPluginInit(int argc, const char *argv[]) {
if (!atscppapi::RegisterGlobalPlugin("netlify", "netlify",
da...@netlify.com") {
return;
}
}
```
I've opened a PullRequest with this change. If this proposal is accepted, I
can update all examples and plugins with the new behavior in the same Pull
Request:
