/*-------------------------------------------------------------------------
 * 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.
 *
 * Return:      Execution time for an API call
