     mblen — get number of bytes in a character

     Standard C Library (libc, -lc)

     #include <stdlib.h>

     mblen(const char *mbchar, size_t nbytes);

     The mblen() function computes the length in bytes of a multibyte charac‐
     ter mbchar according to the current conversion state.  Up to nbytes bytes
     are examined.

     A call with a null mbchar pointer returns nonzero if the current locale
     requires shift states, zero otherwise; if shift states are required, the
     shift state is reset to the initial state.

     If mbchar is NULL, the mblen() function returns nonzero if shift states
     are supported, zero otherwise.

     Otherwise, if mbchar is not a null pointer, mblen() either returns 0 if
     mbchar represents the null wide character, or returns the number of bytes
     processed in mbchar, or returns -1 if no multibyte character could be
     recognized or converted.  In this case, mblen()'s internal conversion
     state is undefined.

     The mblen() function will fail if:

     [EILSEQ]		An invalid multibyte sequence was detected.

     [EINVAL]		The internal conversion state is not valid.

     mbrlen(3), mbtowc(3), multibyte(3)

     The mblen() function conforms to ISO/IEC 9899:1999 (“ISO C99”).
