      Function discards any whitespace characters until first non-whitespace character is found. Then it takes as many characters as possible to form a valid base-n (where n=base) integer number representation and converts them to an integer value. The valid integer value consists of the following parts:

      • (opcional) plus or minus sign
      • (opcional) prefix (0) indicating octal base (applies only when the base is 8)
      • (opcional) prefix (0x or 0X) indicating hexadecimal base (applies only when the base is 16)
      • a sequence of digits

      The set of valid digits for base-2 integer is 01, for base-3 integer is 012, and so on. For bases larger than 10, valid digits include alphabetic characters, starting from Aa for base-11 integer, to Zz for base-36 integer. The case of the characters is ignored.

      As funções define o ponteiro apontado pelo str_end para apontar para o caractere largo passado o último personagem interpretado. Se str_end é NULL, ele é ignorado.
      Original:
      The functions sets the pointer pointed to by str_end to point to the wide character past the last character interpreted. If str_end is NULL, it is ignored.
