asys

asynchronous system APIs

20

21 of 54

Current system APIs

No asynchrony (have to create threads manually)

Lacking file system functionality (e.g. chmod)

Hard-to-use TCP/UDP sockets

Hard-to-use processes

No IPC sockets

21

22 of 54

Solutions?

How to design the API?

How to implement it consistently across many different sys targets?

How to represent asynchrony?
