It appears to be a GNU / Linux function.  It does the obvious thing -
returns the length of a length-limited but possibly not
null-terminated string.

Something like this (untested) should do:

size_t strnlen(const char *s, size_t n)
{
    size_t i;

    for(i=0; i<n; i++)
        if(s[i] == 0)
            break;

    return i;
}
