How thread-safe is fishhook

[michaeleisel]

I want to hook pthread_create in main, but I'm curious if there can be any tearing or otherwise bugs due to thread safety. I don't mind if it's undefined whether concurrent calls use the old or the new function, I just want to be sure that there won't be any peripheral bugs.

If you hook in main (i.e., before any other threads are created), how would there be any concurrent calls?

Fair point

Sounds like that answered your question, so closing. Thanks for asking!
