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:
- (optional) plus or minus sign
- (optional) prefix (
0) indicating octal base (applies only when the base is8) - (optional) prefix (
0xor0X) indicating hexadecimal base (applies only when the base is16) - 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.
Die Funktionen setzt den Zeiger auf die durch
str_end auf die weite Zeichen nach dem letzten Zeichen interpretiert zeigen. Wenn str_end NULL ist, wird es ignoriert .Original:
