DESCRIPTION
The atol() function converts the initial portion of the string pointed to by str to long integer representation.
It is equivalent to:
strtol(str, (char **)NULL, 10);
The atoll() function converts the initial portion of the string pointed to by str to long long integer representation.
It is equivalent to:
strtoll(str, (char **)NULL, 10);
While the atol() and atoll() functions use the current locale, the atol_l() and atoll_l() functions may be passed locales directly. See
xlocale(3) for more information.
ERRORS
The functions atol() and atoll() need not affect the value of errno on an error.
