Detailed Description

Functions to measure time.

On the PPU gettimeofday from time.h is used. On the SPU either also gettimeofday or the spu-timer-library is used depending on the configuration during compilation of the MOC-library. When gettimeofday is used on the SPU the time is global in the MOC-environment with the disadvantage that the SPU-threads get their times from the PPU using DMA causing inaccuracy and delays.

Functions
double	MOC_Wtime (void)
	Returns a floating-point number of seconds, representing elapsed wall-clock time since some time in the past.
double	MOC_Wtick (void)
	Returns the resolution of Moc_Wtime in seconds.
