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
would be better (but less portable) to use @code{strchrnul} in this
case, though.
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.
