When Parrot's being embedded I can see the following functions needing overriding by the embedder:
*) Memory: malloc, realloc, calloc, free *) Signals: handler register, Handler un-register, signal raise, alarm set *) Files: Open, close, seek, tell, read, write. (Possibly asynchronously)
*) Environment: getenv, setenv
Good point.
*) Threading/Process manipulation? (fork, spawn, wait, pthread_*) (Consider
an application built on a runtime that expects to know about all threads
in a process, or an embedder who wants to let their Parrot programs call
back into the main program or integrate into their main event loop.)
I'm not so sure about these, though I can see wanting to override them. I think I'll leave them off for now and we can add them later.
* Networking: socket, accept, connect, listen, etc. (see "Files")
Yeah, and this'll be ever so much fun too. We need to add in select and poll to that list.
A good place to look at for the complete list is Perl 5's system abstraction layer.
Yeah. If you've got time to get a list I'd very much appreciate it. -- Dan
