Convert string to long integer

Convert string to long integer

For example, if we have 0xFFFFFFFE the result would be 4294967294. On success, the function returns the converted integral number as a long int value. If no valid conversion could be performed, a zero value is returned (0L). If the value read is out of the range of representable values by a long int, the function returns LONG_MAX or LONG_MIN (defined in climits), and errno is set to ERANGE.
