|
ANSI_SYNOPSIS
|
|
#include <stdlib.h>
|
|
long long atoll(const char *<[str]>);
|
|
long long _atoll_r(struct _reent *<[ptr]>, const char *<[str]>);
|
|
|
|
TRAD_SYNOPSIS
|
|
#include <stdlib.h>
|
|
long long atoll(<[str]>)
|
|
const char *<[str]>;
|
|
|
|
long long _atoll_r(<[ptr]>, <[str]>)
|
|
struct _reent *<[ptr]>;
|
|
const char *<[str]>;
|
|
|
|
DESCRIPTION
|
|
The function <<atoll>> converts the initial portion of the string
|
|
pointed to by <<*<[str]>>> to a type <<long long>>. A call to
|
|
atoll(str) in this implementation is equivalent to
|
|
strtoll(str, (char **)NULL, 10) including behavior on error.
|
|
|
|
The alternate function <<_atoll_r>> is a reentrant version. The
|
|
extra argument <[reent]> is a pointer to a reentrancy structure.
|
|
|
|
|
|
RETURNS
|
|
The converted value.
|
|
|
|
PORTABILITY
|
|
<<atoll>> is ISO 9899 (C99) and POSIX 1003.1-2001 compatable.
|
|
|
|
No supporting OS subroutines are required.
