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) unsigned integer number representation and converts them to an integer value. The valid unsigned integer value consists of the following parts: None

• (オプション) prefix (0) indicating octal base (applies only when the base is 8)
• (オプション) 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.

ない最初の文字のインデックスにposに格納されています。NULLがposとして渡された場合、それは無視される.

Original:

The index of the first unconverted character is stored in pos. If NULL is passed as pos, it is ignored.
