/* Converts an entire Unicode string, possibly including NUL units, from a
Unicode encoding to a given encoding.
Converts a memory region to encoding TOCODE. TOCODE is as for
iconv_open(3).
The input is in the memory region between SRC (inclusive) and SRC + SRCLEN
(exclusive).
If OFFSETS is not NULL, it should point to an array of SRCLEN integers; this
array is filled with offsets into the result, i.e. the character starting
at SRC[i] corresponds to the character starting at (*RESULTP)[OFFSETS[i]],
and other offsets are set to (size_t)(-1).
*RESULTP and *LENGTH should initially be a scratch buffer and its size,
or *RESULTP can initially be NULL.
May erase the contents of the memory at *RESULTP.
Return value: 0 if successful, otherwise -1 and errno set.
If successful: The resulting string is stored in *RESULTP and its length
in *LENGTHP. *RESULTP is set to a freshly allocated memory block, or is
unchanged if no dynamic memory allocation was necessary.
Particular errno values: EINVAL, EILSEQ, ENOMEM. */
