	GUID (StringParam pchGUID)
	Convert a GUID string into a GUID structure.

std::string	ToString () const
	Get an ASCII string representation for a given GUID.

Detailed Description

If the device is detached and then re-attached to a different port, or if the base system is rebooted, the device should still report the same GUID.

GUIDs are as precise as possible but are not guaranteed to distinguish physically distinct but equivalent devices. For example, two game controllers from the same vendor with the same product ID and revision may have the same GUID.

GUIDs may be platform-dependent (i.e., the same device may report different GUIDs on different operating systems).

Since: This struct is available since SDL 3.2.0.
