20.15.1 IO Spaces

GNU poke supports the abstract notion of IO space, which is an addressable space of Poke objects: integers, strings, arrays, structs, etc. This underlying storage for the IO spaces (which we call IO devices) can be heterogeneous: from a file your file system to the memory of some process.

• open  Creating IO spaces.
• opensub  IO sub spaces.
• openproc  IO proc spaces.
• close  Destroying IO spaces.
• flush  Flushing IO spaces.
• get_ios  Getting the current IO space.
• set_ios  Setting the current IO space.
• iolist  Getting a list of open IO spaces.
• openset  Opening and setting combined.
• iosize  Getting the size of an IO space.
• iohandler  Getting the handler string of an IO space.
• ioflags  Getting the flags of an IO space.
• IO Space Hooks  Hooking in common operations on IO spaces.
