242 | portion of the string pointed to by nptr to long int, long long int,\r | |
243 | unsigned long int, and unsigned long long int representation, respectively.\r | |
244 | First, they decompose the input string into three parts: an initial,\r | |
245 | possibly empty, sequence of white-space characters (as specified by the\r | |
246 | isspace function), a subject sequence resembling an integer represented in\r | |
247 | some radix determined by the value of base, and a final string of one or\r | |
248 | more unrecognized characters, including the terminating null character of\r | |
249 | the input string. Then, they attempt to convert the subject sequence to an\r | |
250 | integer, and return the result.\r | |
251 | \r | |
252 | If the value of base is zero, the expected form of the subject sequence is\r | |
253 | that of an integer constant as described in 6.4.4.1, optionally preceded\r | |
254 | by a plus or minus sign, but not including an integer suffix. If the value\r | |
255 | of base is between 2 and 36 (inclusive), the expected form of the subject\r | |
256 | sequence is a sequence of letters and digits representing an integer with\r | |
257 | the radix specified by base, optionally preceded by a plus or minus sign,\r | |
258 | but not including an integer suffix. The letters from a (or A) through z\r | |
259 | (or Z) are ascribed the values 10 through 35; only letters and digits whose\r | |
260 | ascribed values are less than that of base are permitted. If the value of\r | |
261 | base is 16, the characters 0x or 0X may optionally precede the sequence of\r | |
262 | letters and digits, following the sign if present.\r | |
263 | \r | |
264 | The subject sequence is defined as the longest initial subsequence of the\r | |
265 | input string, starting with the first non-white-space character, that is of\r | |
266 | the expected form. The subject sequence contains no characters if the input\r | |
267 | string is empty or consists entirely of white space, or if the first\r | |
268 | non-white-space character is other than a sign or a permissible letter or digit.\r | |
269 | \r | |
270 | If the subject sequence has the expected form and the value of base is\r | |
271 | zero, the sequence of characters starting with the first digit is\r | |
272 | interpreted as an integer constant. If the subject sequence has the\r | |
273 | expected form and the value of base is between 2 and 36, it is used as the\r | |
274 | base for conversion, ascribing to each letter its value as given above. If\r | |
275 | the subject sequence begins with a minus sign, the value resulting from the\r | |
276 | conversion is negated (in the return type). A pointer to the final string\r | |
277 | is stored in the object pointed to by endptr, provided that endptr is\r | |
278 | not a null pointer.\r | |
