* debugging and performance analysis. When this flag is set
* to TRUE, it means that the log file is open and ready to

* Since much of the code supporting the parallel metadata

* H5C. Instead, H5AC reads the trace_file_ptr as needed.

* currently_logging: Boolean flag that indicates if cache operations are

* log_file_ptr: File pointer pointing to the log file. The I/O functions
* in stdio.h are used to write to the log file regardless of
* the VFD selected.
*
* aux_ptr: Pointer to void used to allow wrapper code to associate
* its data with an instance of H5C_t. The H5C cache code
* sets this field to NULL, and otherwise leaves it alone.
