mbtowc(wchar_t *,const char *,size_t)
IMPORT_C int mbtowc(wchar_t *pwc, const char *s, size_t n);
Description
Converts the multibyte character addressed by s into the corresponding UNICODE character pwc
Parameters
wchar_twchar_t *pwc |
Is the address of a wide character, type wchar_t, to receive the UNICODE equivalent of s.
|
const char *s |
Points to the multibyte character to be converted to UNICODE.

mbstowcs(wchar_t *,const char *,size_t)
IMPORT_C int mbstowcs(wchar_t *pwc, const char *s, size_t n);
Description
Parameters
Return value
wcstombs(char *,const wchar_t *,size_t)
IMPORT_C int wcstombs(char *s, const wchar_t *pwc, size_t n);
Description
The wcstombs function converts a wide string to a string of multibyte characters.
Parameters
Return value
mblen(const char *,size_t)
IMPORT_C int mblen(const char *string, size_t size);
Description
If string is not a null pointer, the function returns the number of bytes in the multibyte string that constitute the next
multibyte character, or it returns -1 if the next n (or the remaining) bytes do not constitute a valid multibyte character.
mblen does not include the terminating null in the count of bytes.
Parameters
Return value
int |
the number of bytes in the multibyte string
|
|
