FUNCTION
<<atoll>>---convert a string to a long long integer
INDEX
atoll
INDEX
_atoll_r
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.
