Declaration
int mblen(const char *str, size_t size);
Function
returns the length (in bytes) of a multibyte character pointed to by str. Only the first size number of characters are examined. It returns -1 on error.
Return
If str is null, then mblen() returns nonzero if multibyte characters have state-dependent encodings. If they do not, zero is returned.
