Closes an outbound half of the channel. When the peer receives all the messages
sent prior to the calling chdone all its subsequent attempts to receive
will fail with EPIPE error.
ch: The channel.
In case of success the function returns 0. In case of error it returns -1 and
sets errno to one of the values below.
- EBADF: Invalid handle.
- ENOTSUP: The handle does not support this operation.
- EPIPE: chdone was already called on this channel.
