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 (
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.
str_end auf das Zeichen nach dem letzten Zeichen interpretiert zeigen. Wenn str_end NULL ist, wird es ignoriert .str_end to point to the character past the last character interpreted. If str_end is NULL, it is ignored.You can help to correct and verify the translation. Click here for instructions.

[Bearbeiten] Rückgabewert
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 .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.You can help to correct and verify the translation. Click here for instructions.
