Re: Path to Shared Library?

Oh, I know the answer to this one. You can make it return the URL or bundle instead. All I cared about was the executable name.

static CFStringRef CopyForestName(void)
{
CFStringRef forestName=NULL;
Dl_info info;
if (dladdr(CopyForestName, &info))
{
const char * libraryName = info.dli_fname;
if (libraryName)
{
CFURLRef url=CFURLCreateFromFileSystemRepresentation(NULL, (UInt8*)libraryName, strlen(libraryName), false);
if (url)
{
CFURLRef macOSFolder=CFURLCreateCopyDeletingLastPathComponent(NULL,url);
if (macOSFolder)
{
CFURLRef contents=CFURLCreateCopyDeletingLastPathComponent(NULL, macOSFolder);
if (contents)
{
CFURLRef bundleURL=CFURLCreateCopyDeletingLastPathComponent(NULL, contents);
if (bundleURL)
{
CFBundleRef bundle=CFBundleCreate(NULL, bundleURL);
if (bundle)
{

forestName=CFBundleGetValueForInfoDictionaryKey(bundle, kCFBundleNameKey);
if (forestName)
CFRetain(forestName);
CFRelease(bundle);
}
}
CFRelease(contents);
}
CFRelease(macOSFolder);
}
CFRelease(url);
}
}
}
return forestName;
}

How can my shared library discover its own location on disk at runtime?

I can get the path to the host application (using GetProcessBundleLocation()), but the relative path from the application to the library may not be constant. (The shared may be used by several applications, for which the relative paths may be different.) Any ideas how I can this?
