mdz_utf32_insertUtf8_async - maxdz-gmbh/mdz_unicode GitHub Wiki

Insert nCount UTF-8 characters in string. UTF-8 characters are converted to UTF-32 characters before isertion. Size grows on added UTF-32 characters count. Length grows on added symbols count.
String reserved area and pcItems should not overlap.

mdz_bool mdz_utf32_insertUtf8_async(
  struct mdz_Utf32* pUtf32,
  size_t nLeftPos,
  const unsigned char* pcItems,
  size_t nCount,
  mdz_bool bReserve,
  struct mdz_asyncData* pAsyncData);

Synchronous version:
mdz_utf32_insertUtf8(pUtf32, nLeftPos, pcItems, nCount, bReserve);

Parameter	Description
pUtf32	pointer to string returned by mdz_utf32_create() or mdz_utf32_create_attached()
nLeftPos	0-based position to insert in symbols. If nLeftPos == Length or -1, items are appended. nLeftPos > Length is not allowed
pcItems	UTF-8 characters to insert
nCount	number of UTF-8 characters to insert in bytes or 0 if pcItems until 0-terminator should be used
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 pUtf32 is 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_utf32_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 pcItems contain invalid UTF-8 character(s) (MDZ_ERROR_CONTENT)
mdz_false	if string reserved area and pcItems overlap (MDZ_ERROR_OVERLAP)
mdz_true	if pcItems == NULL (MDZ_ERROR_ITEMS), or nCount == 0 (MDZ_ERROR_ZEROCOUNT), or nLeftPos > Length (MDZ_ERROR_BIGLEFT). No insertion is made
mdz_true	insertion succeeded
