/**
|
|
* Appends character or word-encoded string to buffer.
|
|
*
|
|
* Up to eight characters can be appended. For example:
|
|
*
|
|
* appendw(&s, 'h'|'i'<<8);
|
|
*
|
|
* Is equivalent to:
|
|
*
|
|
* appends(&s, "hi");
|
|
*
|
|
* The special case:
|
|
*
|
|
* appendw(&s, 0);
|
|
*
|
|
* Will append a single NUL character.
|
|
*
|
|
* The resulting buffer is guaranteed to be NUL-terminated, i.e.
|
|
* `!b[appendz(b).i]` will be the case.
|
|
*
|
|
* @return bytes appended or -1 if `ENOMEM`
