mblen

Item Value Header file stdlib.h 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.
