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:
- (オプション) plus or minus sign
- (オプション) prefix (
0) indicating octal base (applies only when the base is 8) - (オプション) prefix (
0xor0X) 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.
関数は、最後の文字の解釈ワイド文字を指すように
str_endが指すポインタを設定します。 str_endNULLである場合、それは無視されます.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.The text has been machine-translated via Google Translate.
