Defined in header
Converts a null-terminated multibyte character sequence, which begins in the conversion state described by
*ps, from the array whose first element is pointed to by
*src to its wide character representation. If
dst is not null, converted characters are stored in the successive elements of the wchar_t array pointed to by
dst. No more than
len wide characters are written to the destination array.
Each multibyte character is converted as if by a call to mbrtowc. The conversion stops if:
- The multibyte null character was converted and stored.
srcis set to NULL and
*psrepresents the initial shift state.
- An invalid multibyte character (according to the current C locale) was encountered.
srcis set to point at the beginning of the first unconverted multibyte character.
- the next wide character to be stored would exceed
srcis set to point at the beginning of the first unconverted multibyte character. This condition is not checked if dst==NULL.
|dst||-||pointer to wide character array where the results will be stored|
|src||-||pointer to pointer to the first element of a null-terminated multibyte string|
|len||-||number of wide characters available in the array pointed to by dst|
|ps||-||pointer to the conversion state object|
On success, returns the number of wide characters, excluding the terminating L'\0', written to the character array.. If dst==NULL, returns the number of wide characters that would have been written given unlimited length.
