//! Second Pass: Allocate memory for pathInfo with respect to the number of pathInfoCount(from First Pass) to fetch
//! targetInfoCount. If sourceModeInfo is needed allocate memory or it can be initialized to NULL.
//! Third Pass(Optional, only required if target information is required): Allocate memory for targetInfo with respect
//! to number of targetInfoCount(from Second Pass).
//! SUPPORTED OS: Windows 7 and higher
// First pass: Figure out how many pathInfo objects there are
