| 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. |
