MDN’s new design is in Beta! A sneak peek:

Guaranteed to be an unsigned 64-bit integer on all platforms.


#include <prtypes.h>

typedef definition PRUint64;


May be defined in several different ways, depending on the platform. For syntax details for each platform, see prtypes.h.


Note: Prior to Gecko 12.0, PRUint64 was actually treated as a signed 64-bit integer by XPConnect. This has been fixed.
