<h3>MBLEN(3)            Linux Programmer's Manual            MBLEN(3)
</h3>

<h3>NAME
</h3>       mblen - determine the number of bytes in a character

<h3>SYNOPSIS
</h3>       #include &lt;stdlib.h&gt;

       int mblen(const char *s, size_t n);

<h3>DESCRIPTION
</h3>       The mblen() function scans the first n bytes of the string
       s and returns the number of bytes  in  a  character.   The
       mblen() function is equivalent to

              mbtowc((wchat_t *)0, s, n);

       except  that  the  shift state of the mbtowc() function is
       not affected.

<h3>RETURN VALUE
</h3>       The mblen() returns the number of bytes in a character  or
       -1 if the character is invalid or 0 if s is a NULL string.

<h3>CONFORMING TO
</h3>       SVID 3, ISO 9899
