[Hdf-forum] accessing low level file descriptor or handle

[Raymond Lu]

Mark,

There's an API function

    /herr_t /|H5Fget_vfd_handle|(/hid_t/ |file_id|, /hid_t/ |fapl_id|, 
/void **/|file_handle| )

for this purpose.  You can find it in the v1.8 Reference Manual:

    http://www.hdfgroup.org/HDF5/doc/RM/RM_H5F.html#File-GetVfdHandle

Thanks.

Ray
