Each probe point tuple is at least a 3-tuple, that is, it has a minimum of three fields.
每个探测点至少包含三个字段。
Each probe clause consists of a probe point specification statement, action block, and an optional predicate.
每个探测子句由一个探测点指定语句、动作块和可选的断言组成。
Trace hooks can be applied at the entry or exit of any function (currently exit probe point is supported for system calls only).
跟踪钩子可以应用于任何函数的入口或出口(当前对于系统调用只支持出口探测点)。
The probe point specification identifies a code location whose execution or an event whose occurrence should trigger the probe actions.
探测点指定语句指定应该触发探测动作的代码位置或事件。
If a trace point also happens to be a probe point (an explicitly identified precise location within a function), the probe number is also included in this string (see trace point 4, for example).
如果一个跟踪点碰巧也是一个探测点(一个函数中被显式地标识出来的一个精确的位置)，那么探测号也将包括到这个字符串中(例如，请查看跟踪点4)。
By placing light probes in your level, it'll sample all of the lighting at each probe point.
通过在场景中布置灯光探测器，可以为每个探测点的光照进行采样。
