getSystemRegistryString()

bool getSystemRegistryString ( const char * keyPath, const char * valueName, std::string & value, std::string * phValue )

static

Read registry string.

This also supports a means to look for high-versioned keys by use of a $VERSION placeholder in the key path. $VERSION in the key path is a placeholder for the version number, causing the highest value path to be searched for and used. I.e. "SOFTWARE\\Microsoft\\VisualStudio\\$VERSION". There can be additional characters in the component. Only the numeric characters are compared. This function only searches HKLM.
