[erlang-questions] Intrusive function intercept
Thu Oct 10 10:02:03 CEST 2013
I would like to monitor a process and suspend the execution of certain
functions to perform some other computation before. For instance consider a
process A which executing the following simple function.
I would like to initiate a process, B, that monitors the execution of A.
I want B to:
1) stop A before function y is executed
2) execute some logic
3) resumes the execution of A (by executing Y and Z)
So far, I have been following this
managed to determine when the y() function call was being done, but
cannot suspend its execution. Any ideas how I can achieve this?
