@deftypefun int strncmp (const char *@var{s1}, const char *@var{s2}, size_t @var{size})
This function is the similar to @code{strcmp}, except that no more than
@var{size} wide characters are compared. In other words, if the two
strings are the same in their first @var{size} wide characters, the
@var{size} characters are compared. In other words, if the two
strings are the same in their first @var{size} characters, the
