/*-------------------------------------------------------------------------
- * Function: HDstrtoll
- *
- * Purpose: Converts the string S to an int64_t value according to the
- * given BASE, which must be between 2 and 36 inclusive, or be
- * the special value zero.
- *
- * The string must begin with an arbitrary amount of white space
- * (as determined by isspace(3c)) followed by a single optional
- * `+' or `-' sign. If BASE is zero or 16 the string may then
- * include a `0x' or `0X' prefix, and the number will be read in
- * base 16; otherwise a zero BASE is taken as 10 (decimal)
- * unless the next character is a `0', in which case it is taken
- * as 8 (octal).
- *
- * The remainder of the string is converted to an int64_t in the
- * obvious manner, stopping at the first character which is not
- * a valid digit in the given base. (In bases above 10, the
- * letter `A' in either upper or lower case represetns 10, `B'
- * represents 11, and so forth, with `Z' representing 35.)
- *
- * If REST is not null, the address of the first invalid
- * character in S is stored in *REST. If there were no digits
- * at all, the original value of S is stored in *REST. Thus, if
- * *S is not `\0' but **REST is `\0' on return the entire string
- * was valid.
- *
- * Return: Success: The result.
- *
- * Failure: If the input string does not contain any
- * digits then zero is returned and REST points
- * to the original value of S. If an overflow
- * or underflow occurs then the maximum or
- * minimum possible value is returned and the
- * global `errno' is set to ERANGE. If BASE is
- * incorrect then zero is returned.
