This function is similar to pthread_cond_wait, except that the third argument is the absolute time value until which the reader thread is willing to wait before it gives up.

这个函数与pthread_cond_wait相似，但是第三个参数是绝对时间值，到达这个时间时读线程自愿放弃等待。

The only byte-oriented arithmetic function on the SPU is absdb, "absolute difference of bytes," which gives the absolute value of the difference between two operands.

SPU 上惟一一个面向字节的计算函数是 absdb（意思是 “absolute difference of bytes”），计算两个操作数间的差的绝对值。

If the value is less than or equal to all other function values, it is an absolute minimum.

如果这个值小于或等于所有其它的函数值，那它就是绝对极小值。
