mdz_utf16_insertUtf16_string_async - maxdz-gmbh/mdz_unicode GitHub Wiki

Insert UTF-16 string pUtf16Source in string. Size grows on nCount. Length grows on symbols count.
String reserved area and pUtf16Source->m_pData should not overlap.
This function performs significantly better than mdz_utf16_insertUtf16_async() - because there is no additional validation of inserted string.

mdz_bool mdz_utf16_insertUtf16_string_async(
  struct mdz_Utf16* pUtf16,
  size_t nLeftPos,
  const struct mdz_Utf16* pUtf16Source,
  mdz_bool bReserve,
  struct mdz_asyncData* pAsyncData);

Synchronous version:
mdz_utf16_insertUtf16_string(pUtf16, nLeftPos, pUtf16Source, bReserve);

Parameter	Description
pUtf16	pointer to string returned by mdz_utf16_create() or mdz_utf16_create_attached()
nLeftPos	0-based position to insert in symbols. "surrogate pairs" count as 1 symbol. If nLeftPos == Length or -1, items are appended. nLeftPos > Length is not allowed
pUtf16Source	pointer to UTF-16 string to insert. String is returned by mdz_utf16_create() or mdz_utf16_create_attached()
bReserve	if mdz_true reserve capacity when there is not enough space for insertion, otherwise mdz_false
pAsyncData	pointer to shared async data for asynchronous call, or NULL if call should be synchronous

Return	Description
mdz_false	if pUtf16 == NULL
mdz_false	if bReserve == mdz_true and memory allocation failed (MDZ_ERROR_ALLOCATION)
mdz_false	if bReserve == mdz_true and there is not enough capacity for inserted data, but m_pData is attached using mdz_utf16_attachData() (MDZ_ERROR_ATTACHED)
mdz_false	if bReserve == mdz_false and there is not enough free Capacity in the string (MDZ_ERROR_CAPACITY)
mdz_false	if string reserved area and pUtf16Source->m_pData overlap (MDZ_ERROR_OVERLAP)
mdz_true	if pUtf16Source == NULL (MDZ_ERROR_SOURCE), or pUtf16Source.Size == 0 (MDZ_ERROR_ZEROCOUNT), or nLeftPos > Length (MDZ_ERROR_BIGLEFT). No insertion is made
mdz_true	insertion succeeded
