poke package:blaze-builder

Changing a sequence of bytes starting from the given pointer. Pokes are the most primitive buffer manipulation. In most cases, you don't use the explicitly but as part of a Write, which also tells how many bytes will be changed at most.

pokeN size io creates a write that denotes the writing of size bytes to a buffer using the IO action io. Note that io MUST write EXACTLY size bytes to the buffer!

Extract the Poke action of a write.
