zx::result<char> ReadChar (bool block)

Read one character.

If |wait| is true, block until a character is read or the thread is asked to suspend or

terminate (ZX_ERR_INTERNAL_INTR_RETRY, ZX_ERR_INTERNAL_INTR_KILLED).

If |wait| is false and no character is ready, ZX_ERR_SHOULD_WAIT is returned.

zx::result<ReadContext> ReadCharWithContext (bool block)

Same as ReadChar(bool block), but returns |ReadContext| instead of just the read character.
