GA_largeInteger

Declaration

typedef u64 GA_largeInteger

Prototype In

snap/graphics.h

Description

Defines the structure for holding 64-bit integers used for storing the values returned by the precision timing functions. The precision timing functions are used internally by the the SNAP Graphics drivers for software stereo support, however the granularity of the timing functions is variable. Generally a granularity of around 1us is desired for maximum accuracy. Where possible these import functions should be implemented using the Intel Pentium RDTSC instruction or equivalent (with time readings normalised to 1us granularity to avoid overflow internally).
