10 | SYNOPSIS |
---|
11 | #include <stdlib.h> |
---|
12 | long long atoll(const char *<[str]>); |
---|
13 | long long _atoll_r(struct _reent *<[ptr]>, const char *<[str]>); |
---|
14 | |
---|
15 | DESCRIPTION |
---|
16 | The function <<atoll>> converts the initial portion of the string |
---|
17 | pointed to by <<*<[str]>>> to a type <<long long>>. A call to |
---|
18 | atoll(str) in this implementation is equivalent to |
---|
19 | strtoll(str, (char **)NULL, 10) including behavior on error. |
---|
20 | |
---|
21 | The alternate function <<_atoll_r>> is a reentrant version. The |
---|
22 | extra argument <[reent]> is a pointer to a reentrancy structure. |
---|
23 | |
---|
24 | |
---|
25 | RETURNS |
---|
26 | The converted value. |
---|
27 | |
---|
28 | PORTABILITY |
---|
29 | <<atoll>> is ISO 9899 (C99) and POSIX 1003.1-2001 compatable. |
---|
30 | |
---|
31 | No supporting OS subroutines are required. |
