The @code{strtol} function converts the string in @var{string} to a
long integer value according to the given @var{base}, which must be
to indicate bases 8 and 16, respectively, else default to base 10.
When the base is 16 (either explicitly or implicitly), a prefix of
@code{0x} is allowed. The handling of @var{endptr} is as that of
-@code{strtod} above.
+@code{strtod} above. The @code{strtoul} function is the same, except
+that the converted value is unsigned.
