The terminating null character is considered to be part of the string,
so you can use this function get a pointer to the end of a string by
-specifying a null character as the value of the @var{c} argument. It

+specifying a null character as the value of the @var{c} argument.

+When @code{strchr} returns a null pointer, it does not let you know
+the position of the terminating null character it has found. If you
+need that information, it is better (but less portable) to use
+@code{strchrnul} than to search for it a second time.
