Legt einen vorzeichenlosen Integer-Wert in einem breiten String, auf den str .

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

• (optional) prefix (0) indicating octal base (applies only when the base is 8)
• (optional) 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.

Die Funktionen setzt den Zeiger auf die durch str_end auf die weite Zeichen nach dem letzten Zeichen interpretiert zeigen. Wenn str_endNULL ist, wird es ignoriert .

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.

Parameter

str	-	Zeiger auf die null-terminierte breite Zeichenfolge interpretiert werden Original: pointer to the null-terminated wide string to be interpreted The text has been machine-translated via Google Translate. You can help to correct and verify the translation. Click here for instructions.
str_end	-	Zeiger auf einen Zeiger auf eine breite Charakter . Original: pointer to a pointer to a wide character. The text has been machine-translated via Google Translate. You can help to correct and verify the translation. Click here for instructions.
base	-	Base der interpretierten Integer-Wert Original: base of the interpreted integer value The text has been machine-translated via Google Translate. You can help to correct and verify the translation. Click here for instructions.

Rückgabewert

Integer-Wert entsprechend dem Inhalt der str auf Erfolg. Wenn der umgewandelte Wert fällt außerhalb der Reichweite des zugehörigen Rückgabetyp tritt Entfernungsfehlers und ULONG_MAX oder ULLONG_MAX zurückgegeben. Wenn keine Umwandlung durchgeführt werden kann, wird zurückgegeben ​0​ .

Original:

Integer value corresponding to the contents of str on success. If the converted value falls out of range of corresponding return type, range error occurs and ULONG_MAX or ULLONG_MAX is returned. If no conversion can be performed, ​0​ is returned.
