  17 /*  SYNOPSIS */
  18         const char * nptr,

  20         int          base)

  22 /*  FUNCTION
  23         Convert a string of digits into an integer according to the
  24         given base. This function is like strtoul() except the fact,
  25         that it returns a value of type uintmax_t.
  26
  27     INPUTS
  28         str - The string which should be converted.
  29         endptr - If this is non-NULL, then the address of the first
  30                 character after the number in the string is stored
  31                 here.
  32         base - The base for the number.
  33
  34     RESULT
  35         The value of the string. The first character after the number
  36         is returned in *endptr, if endptr is non-NULL. If no digits can
  37         be converted, *endptr contains str (if non-NULL) and 0 is
  38         returned.
