mdz_wchar_insertWchar_string_async - maxdz-gmbh/mdz_unicode GitHub Wiki

Insert "wide"-characters string pWcharSource in string. Size grows on nCount. Length grows on symbols count.
String reserved area and pWcharSource->m_pData should not overlap.

mdz_bool mdz_wchar_insertWchar_string_async(
  struct mdz_Wchar* pWchar,
  size_t nLeftPos,
  const struct mdz_Wchar* pWcharSource,
  mdz_bool bReserve,
  struct mdz_asyncData* pAsyncData);

Synchronous version:
mdz_wchar_insertWchar_string(pWchar, nLeftPos, pWcharSource, bReserve);

Parameter	Description
pWchar	pointer to string returned by mdz_wchar_create() or mdz_wchar_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
pWcharSource	pointer to "wide"-characters string to insert. String is returned by mdz_wchar_create() or mdz_wchar_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 pWchar == 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_wchar_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 pWcharSource->m_pData overlap (MDZ_ERROR_OVERLAP)
mdz_true	if pWcharSource == NULL (MDZ_ERROR_SOURCE), or pWcharSource.Size == 0 (MDZ_ERROR_ZEROCOUNT), or nLeftPos > Length (MDZ_ERROR_BIGLEFT). No insertion is made
mdz_true	insertion succeeded
