Erlang 跟踪器源代码
有谁知道哪些 Erlang 源文件负责其跟踪器（trace BIF）。
我正在研究 Erlang 中同步跟踪的可能性（其中受监视的进程等待接收跟踪消息的监视进程的继续）。现在我正在尝试决定是尝试修改 Erlang 的源代码还是为此类事情生成一个解析器。任何反馈将不胜感激。
谢谢。
Does anybody know which Erlang source files are responsible for its tracer (the trace BIF).
I am looking into the possibility of synchronous tracing in Erlang (where the monitored process waits for go-ahead from the monitoring process receiving the trace messages). For now I'm trying to decide whether to try modifying Erlang's source code or generate a parser for this sort of thing. Any feedback would be appreciated.
Thanks.

我相信您想首先查看 erts/emulator/beam/erl_bif_trace.c，因为它实现了
trace/3和朋友。 （例如，trace/3由 C 函数trace_3()实现。）您可能还对
erl_trace.c感兴趣，它看起来是为模拟器做大量跟踪工作的函数。I believe you want to look at
erts/emulator/beam/erl_bif_trace.cfirst, as that implementstrace/3and friends. (trace/3is implemented by the C functiontrace_3(), for example.)You may also be interested in
erl_trace.c, which looks to be the functions that do a lot of the tracing work for the emulator.
