@deftypefun {unsigned long int} strtoul (const char *@var{string}, char **@var{tailptr}, int @var{base})
The @code{strtoul} (``string-to-unsigned-long'') function is like
@code{strtol} except it deals with unsigned numbers, and returns its
value with type @code{unsigned long int}. No @samp{+} or @samp{-} sign
may appear before the number, but the syntax is otherwise the same as
value with type @code{unsigned long int}. If the number has a leading
@samp{-} sign the negated value is returned. The syntax is the same as
described above for @code{strtol}. The value returned in case of
overflow is @code{ULONG_MAX} (@pxref{Range of Type}).
Like @code{strtol} this function sets @code{errno} and returns the value
@code{0ul} in case the value for @var{base} is not in the legal range.
For @code{strtoul} this can happen in another situation. In case the
number to be converted is negative @code{strtoul} also sets @code{errno}
to @code{EINVAL} and returns @code{0ul}.
