Question about the capabilities of gawk extensions

[Ari Abrams]

Hello,

I essentially just want to confirm that there isn't a way to do what I am
trying to do with a gawk extension. What I am trying to do is implement
custom signal handling in gawk. I was pointed to this email from a Stack
Overflow post I made which I will link at the end. After reading the gawk
extension documentation, I have not found a way to call user defined gawk
functions from an extension. This would be necessary for signal handling
since the user would need to somehow register a gawk function as a callback
to be called when the process receives a signal. Is this at all possible?

Thanks.
