Overview
The atou64() function converts a string to a 64-bit unsigned integer.
Return value
The atou64() function returns 0 if successful or -1 if the string is not a valid 64-bit unsigned integer.
Check errno to see what error occurred.
Notes
None of the libabz routines are thread-safe. I'm not planning to change this either! For more information, please see http://threading.2038bug.com/
Please note that atou64() automatically converts octal (preceded by 0) and hexadecimal (preceded by 0x) numbers, so 077 is not 77, but rather 63.
