30 | DESCRIPTION |
||
31 | The function < |
||
32 | a < |
||
33 | leading whitespace, which is ignored; a subject string consisting |
||
34 | of characters resembling an integer in the radix specified by <[base]>; |
||
35 | and a trailing portion consisting of zero or more unparseable characters, |
||
36 | and always including the terminating null character. Then, it attempts |
||
37 | to convert the subject string into a < |
||
38 | result. |
||
39 | |||
40 | If the value of <[base]> is 0, the subject string is expected to look |
||
41 | like a normal C integer constant: an optional sign, a possible `<<0x>>' |
||
42 | indicating a hexadecimal base, and a number. If <[base]> is between |
||
43 | 2 and 36, the expected form of the subject is a sequence of letters |
||
44 | and digits representing an integer in the radix specified by <[base]>, |
||
45 | with an optional plus or minus sign. The letters <>--< |
||
46 | equivalently, <>--< |
||
47 | only letters whose ascribed values are less than <[base]> are |
||
48 | permitted. If <[base]> is 16, a leading <<0x>> is permitted. |
||
49 | |||
50 | The subject sequence is the longest initial sequence of the input |
||
51 | string that has the expected form, starting with the first |
||
52 | non-whitespace character. If the string is empty or consists entirely |
||
53 | of whitespace, or if the first non-whitespace character is not a |
||
54 | permissible letter or digit, the subject string is empty. |
||
55 | |||
56 | If the subject string is acceptable, and the value of <[base]> is zero, |
||
57 | < |
||
58 | string with a leading <<0x>> is treated as a hexadecimal value; a string with |
||
59 | a leading 0 and no < |
||
60 | treated as decimal. If <[base]> is between 2 and 36, it is used as the |
||
61 | conversion radix, as described above. If the subject string begins with |
||
62 | a minus sign, the value is negated. Finally, a pointer to the first |
||
63 | character past the converted subject string is stored in <[ptr]>, if |
||
64 | <[ptr]> is not < |
||
65 | |||
66 | If the subject string is empty (or not in acceptable form), no conversion |
||
67 | is performed and the value of <[s]> is stored in <[ptr]> (if <[ptr]> is |
||
68 | not < |
||
69 | |||
70 | The alternate function <<_strtoll_r>> is a reentrant version. The |
||
71 | extra argument <[reent]> is a pointer to a reentrancy structure. |
||
72 | |||
73 | RETURNS |
||
74 | < |
||
75 | made, 0 is returned. |
||
76 | |||
77 | < |
||
78 | the converted value is too large, and sets < |
||
79 | |||
80 | PORTABILITY |
||
81 | < |
||
82 | |||
83 | No supporting OS subroutines are required. |
