Cool.
PicoGUI will need, from the top of my head:
- C standard library functions including the printf family, malloc and
friends, and standard file I/O
- Several miscellaneous functions including timers, shared memory,
and directory tree traversal- fortunately much of this can be safely
omitted, and it's all quarantined within the 'pgserver/os' directory.
- BSD sockets. All the networking code in PicoGUI currently assumes
BSD-compatible sockets, as also provided by Linux, IRIX, and (sort of)
win32. This will be eliminated when the network code is refactored.
This includes the use of select() to wait on multiple sockets and/or
input devices.
