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.
