Count the bytes in a multibyte character (restartable)
size_t mbrlen( const char * s,
mbstate_t * ps);
- A pointer to a multibyte character.
- The maximum number of bytes that you want to count.
- An internal pointer that lets mbrlen() be a restartable
if ps is NULL, mbrlen() uses its own

The mbrlen() function counts the bytes in the multibyte
character pointed to by s, to a maximum of n bytes.
- The resulting conversion state indicates an incomplete multibyte character after all
n characters were converted.
- The function detected an encoding error before completing the next
multibyte character, in which case the function
and leaves the resulting conversion state undefined.
- The next completed character is a null character, in which case the resulting conversion state is the initial conversion state.
- The number of bytes needed to complete the next multibyte
character, in which case the resulting conversion state indicates that x bytes have been converted.
- Invalid character sequence.
- The ps argument points to an invalid object.
