ATOI(3)

NAME
atoi, atoi_l - convert ASCII string to integer

LIBRARY
libc

SYNOPSIS
#include <stdlib.h>
int
atoi(const char *nptr);
#include <xlocale.h>
int
atoi_l(const char *nptr, locale_t loc);

DESCRIPTION
The atoi() function converts the initial portion of the string pointed to by nptr to int representation.

It is equivalent to:

    (int)strtol(nptr, NULL, 10);

The atoi() function has been deprecated by strtol() and should not be used in new code.

The _l-suffixed version takes an explicit locale argument, whereas the non-suffixed version use the current global or per-thread locale.

ERRORS
The function atoi() need not affect the value of errno on an error.
