 * 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.

/*-------------------------------------------------------------------------
 * Function:	H5_trace
 *
 * Purpose:	This function is called whenever an API function is called
 *		and tracing is turned on.  If RETURNING is non-zero then
 *		the caller is about to return and RETURNING points to the
 *              time for the corresponding function call event.  Otherwise
 *              we print the function name and the arguments.
 *
 *		The TYPE argument is a string which gives the type of each of
 *		the following argument pairs.  Each type is zero or more
 *		asterisks (one for each level of indirection, although some
 *		types have one level of indirection already implied) followed
 *		by either one letter (lower case) or two letters (first one
 *		uppercase).
 *
 *		The variable argument list consists of pairs of values. Each
 *		pair is a string which is the formal argument name in the
 *		calling function, followed by the argument value.  The type
 *		of the argument value is given by the TYPE string.
 *
 * Note:	The TYPE string is meant to be terse and is generated by a
 *		separate perl script.
 *
 * WARNING:	DO NOT CALL ANY HDF5 FUNCTION THAT CALLS FUNC_ENTER(). DOING
 *		SO MAY CAUSE H5_trace() TO BE INVOKED RECURSIVELY OR MAY
 *		CAUSE LIBRARY INITIALIZATIONS THAT ARE NOT DESIRED.

 * Modifications:

 *		Added the `a' type letter for haddr_t arguments and `Mt' for
 *		H5FD_mem_t arguments.
 *
 * 		Robb Matzke, 1999-10-25
 *		The `Ej' and `En' types are H5E_major_t and H5E_minor_t error
 *		types. We only print the integer value here.
