153 * of the "out" xbuf is not used, which reserves space for a trailing '\0'
154 * (though it is up to the caller to store a trailing '\0', as needed).
156 * We return a 0 on success or a -1 on error. An error also sets errno to
157 * E2BIG, EILSEQ, or EINVAL (see below); otherwise errno will be set to 0.
158 * The "in" xbuf is altered to update ".pos" and ".len". The "out" xbuf has
159 * data appended, and its ".len" incremented (see below for a ".size" note).
161 * If ICB_CIRCULAR_OUT is set in "flags", the chars going into the "out" xbuf
162 * can wrap around to the start, and the xbuf may have its ".size" reduced
163 * (presumably by 1 byte) if the iconv code doesn't have space to store a
164 * multi-byte character at the physical end of the ".buf" (though no reducing
165 * happens if ".pos" is <= 1, since there is no room to wrap around).
167 * If ICB_EXPAND_OUT is set in "flags", the "out" xbuf will be allocated if
168 * empty, and (as long as ICB_CIRCULAR_OUT is not set) expanded if too small.
169 * This prevents the return of E2BIG (except for a circular xbuf).
171 * If ICB_INCLUDE_BAD is set in "flags", any badly-encoded chars are included
172 * verbatim in the "out" xbuf, so EILSEQ will not be returned.
174 * If ICB_INCLUDE_INCOMPLETE is set in "flags", any incomplete multi-byte
175 * chars are included, which ensures that EINVAL is not returned.
