mdz_utf8_insertUtf8_string_async - maxdz-gmbh/mdz_unicode GitHub Wiki

Insert UTF-8 string pUtf8Source in string. Size grows on nCount. Length grows on symbols count.
String reserved area and pUtf8Source->m_pData should not overlap.
This function performs significantly better than mdz_utf8_insertUtf8_async() - because there is no additional validation of inserted string.

mdz_bool mdz_utf8_insertUtf8_string_async(
  struct mdz_Utf8* pUtf8,
  size_t nLeftPos,
  const struct mdz_Utf8* pUtf8Source,
  mdz_bool bReserve,
  struct mdz_asyncData* pAsyncData);

Synchronous version:
mdz_utf8_insertUtf8_string(pUtf8, nLeftPos, pUtf8Source, bReserve);

Parameter	Description
pUtf8	pointer to string returned by mdz_utf8_create() or mdz_utf8_create_attached()
nLeftPos	0-based position to insert in symbols. If nLeftPos == Length or -1, items are appended. nLeftPos > Length is not allowed
pUtf8Source	pointer to UTF-8 string to insert. String is returned by mdz_utf8_create() or mdz_utf8_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 pUtf8 == 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_utf8_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 pUtf8Source->m_pData overlap (MDZ_ERROR_OVERLAP)
mdz_true	if pUtf8Source == NULL (MDZ_ERROR_SOURCE), or pUtf8Source.Size == 0 (MDZ_ERROR_ZEROCOUNT), or nLeftPos > Length (MDZ_ERROR_BIGLEFT). No insertion is made
mdz_true	insertion succeeded
