ATOLL(3)

NAME
atoll, _atoll_r - convert a string to a long long integer

SYNOPSIS

#include <stdlib.h>

long long atoll(const char *str);

long long _atoll_r(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.
