+ * Function: HDfprintf
+ *
+ * Purpose: Prints the optional arguments under the control of the format
+ * string FMT to the stream STREAM. This function takes the
+ * same format as fprintf(3c) with a few added features:
+ *
+ * The conversion modifier `H' refers to the size of an
+ * `hsize_t' or `hssize_t' type. For instance, "0x%018Hx"
+ * prints an `hsize_t' value as a hex number right justified and
+ * zero filled in an 18-character field.
+ *
+ * The conversion `a' refers to an `haddr_t' type.
+ *
+ * Return: Success: Number of characters printed
+ *
+ * Failure: -1
+ *
+ * Programmer: Robb Matzke
+ * Thursday, April 9, 1998
+ *
+ * Modifications:
+ * Robb Matzke, 1999-07-27
+ * The `%a' format refers to an argument of `haddr_t' type
+ * instead of `haddr_t*' and the return value is correct.

+ * 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.
