Hi Nitya,

(Sorry that I missed your other question.)

H5P_DEFAULT is defined as 0 in H5public.h which is #include by hdf5.h.
It represents the default value of all Property Lists and its effect depends on
what function API you are calling.

In your case, the default file access property is the default VFL (Virtual File 
Layer).
And the binary you used has it set to using the sec2 VFL which is same as the 
posix
API of open/close/read/write/lseek/etc..

This VFL should be able and has been tested to handle files larger than 32bit 
size files.

But I will first try to repeat the failure.
